Abstract
Cash assistance allocations from Temporary Assistance for Needy Families (TANF) and its predecessor program fell from $34.3 billion to $7.4 billion in real value from 1993 to 2016, a 78% decrease. Some investigations of TANF point to favorable labor market changes as the source of the decline, whereas others point to declining benefit levels and barriers to benefit receipt. This study introduces a framework to decompose the decline of TANF cash assistance into changes in need for cash assistance, the participation rate among those meeting income-based eligibility standards, and benefit levels among those receiving cash support. Using the U.S. Current Population Survey, I find that declining participation explains 52% of the decline in TANF cash assistance from 1993 onward, whereas declining need explains 21%, and declining benefit levels explain 27%. The study then applies reweighting techniques to measure the extent to which compositional changes in the population, such as rising employment rates among single mothers, can explain changes in need, participation, and benefit levels. The results suggest that compositional changes explain only 22% of the decline of TANF cash assistance, confirming that the majority of the decline is due to reduced participation and benefit levels rather than reduced demand for cash support. Adding the noncompositional share of the decline in TANF back to observed levels of cash spending in 2016 would result in nearly $20 billion in additional transfers, more than the minimum amount necessary to lift all single-mother households out of poverty.
Introduction
The provision of cash assistance to low-income families is widely acknowledged as an essential tool for combating child poverty and material hardship. Cross-national research demonstrates that countries that offer the most redistributive support for households with children tend to have lower levels of child poverty (Bradbury and Jäntti 1999; Brady et al. 2017; Rainwater and Smeeding 2003). Within the United States, cross-state research has shown that more generous cash assistance schemes contribute to lower levels of hunger, material deprivation, and income poverty among families (Duncan and Magnuson 2013; National Academy of Sciences 2019; Parolin 2019b; Shaefer et al. 2019). After the introduction of the Temporary Assistance for Needy Families (TANF) program in 1996, however, the provision of means-tested cash assistance for jobless, able-bodied families in the United States rapidly declined. In 1993, just three years before the passage of the legislation that introduced TANF, annual cash assistance allocations amounted to $34.3 billion (in 2016 U.S. dollars). By 2016, annual cash assistance allocations had declined to $7.8 billion, a 78% decrease from 1993, despite the relative stability of total TANF spending over time (Floyd et al. 2017; Social Security Administration 2005).
The sources of the decline of TANF cash assistance are contested. Some studies have pointed to rising employment rates of single mothers and the declining incidence of single motherhood as explanations for declines in cash assistance (Haskins 2016; Haskins and Weidinger 2019). Conversely, some studies have pointed to declining benefit values, strict participation requirements, and stringent sanction policies as the primary source of decline (Edin and Shaefer 2016; Schram et al. 2003; Shaefer et al. 2019; Soss et al. 2011). Others have pointed to the fact that inflation has cut the real value of states' TANF block grants by one-third, forcing states to use more of their own resources to maintain stable levels of TANF spending (McCabe 2019).
This study decomposes the sources of the decline in cash assistance from TANF. In doing so, it adjudicates these competing perspectives of the decline of cash assistance and provides precise estimates on the extent to which changes in the composition of the population, changes in employment rates, or changes in policy choices have contributed to the aggregate decline in cash support from TANF. The results provide clarity on the evolution of cash assistance within the TANF program and provide broader evidence on the role of welfare reform in shaping trends in poverty in the United States.
This study proceeds in two analytical steps. First, I introduce an accounting framework to fully decompose changes in cash assistance allocations into changes in four components: (1) the number of households in the population, (2) the share of households meeting the income-based eligibility standards for TANF cash assistance (need), (3) the share of households meeting the income-based eligibility standards that receive cash assistance (participation), and (4) the mean benefit levels among the households receiving TANF (benefit levels). This accounting framework is applied to answer the study's first question: are changes in need, participation rates, or benefit levels of TANF more consequential in explaining the decline of cash assistance from 1993 to 2016?
The second research question builds on the first and asks, to what extent can changes in the demographic and labor market characteristics of the U.S. population explain changes in need, participation, and levels of benefit receipt? I apply reweighting techniques introduced in DiNardo et al. (1996) to estimate how compositional and labor market changes, such as rising employment rates among single mothers, have shaped trends in cash assistance allocations.
The study has three main findings and contributions to the broader social policy literature. First, declining participation rates among households that meet the income-based eligibility requirements for TANF explain the majority (52%) of the decline in cash assistance from 1993 onward, whereas declining need and benefit generosity explain 21% and 27%, respectively. Put differently, only about one-fifth of the decline of cash assistance from TANF can be attributed to improved living standards among low-income families, casting doubt on claims made in more favorable evaluations of TANF (Haskins, 2016). Second, a decomposition analysis suggests that only 22% of the decline of TANF allocations can be explained by changes in the composition of the population, confirming that the vast majority of the decline is due to reduced access and benefit levels rather than reduced need. Finally, adding the noncompositional share of the decline in TANF back to observed levels of TANF cash allocations in 2016 would result in $19.2 billion in additional cash spending, more than the minimum amount necessary to lift all single-mother households out of poverty.
Notably, the counterfactual addition of $19.2 billion in cash assistance, combined with observed spending on cash assistance, is still less than the total funds that states currently spend on all activities within the TANF program (around $31 billion in 2016). This fact suggests that the declining real value of states' TANF block grants is not the most important factor in shaping declines in TANF cash assistance. State governments have enough resources within the TANF program today to make notable reductions in child poverty.
Background
The Decline of Cash Assistance
TANF was signed into law in 1996 as part of the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) and was implemented in all states the following year. Whereas TANF's predecessor, Aid to Families with Dependent Children (AFDC), offered an entitlement to cash assistance for families with incomes below a given threshold, TANF enforces work, education, and training requirements to promote employment and the formation of two-parent families (Falk 2016b).
TANF plays a unique role in the American welfare state. Unlike benefits from the Supplemental Nutrition Assistance Program (SNAP), an important anti-poverty program, cash assistance from TANF can be used on a wide array of household needs rather than simply food items. While access to health insurance through Medicaid is certainly a valuable resource for low-income families, health insurance has a far different effect on most households' consumption capabilities than a monthly cash payment. Meanwhile, refundable tax credits, such as the Earned Income Tax Credit (EITC), are conditional on employment and administered annually rather than monthly. Each of these other safety net programs is important for the well-being of low-income families, but these programs operate differently than cash-based, monthly distributed social assistance for low-income families (Wimer et al. 2020).
The legislation that introduced TANF set out to reduce caseloads and succeeded in that aim. From 1994 to 2016, the number of families receiving AFDC/TANF dropped from 5.1 million to 1.3 million (Falk 2016b). Specifically, PRWORA transformed three core components of state-administered social assistance. First, it strengthened the conditionality requirements attached to the receipt of cash assistance. Under TANF, cash assistance recipients are required to engage in “work participation activities” or employment to continue receiving cash support beyond a certain duration (Falk 2014). Second, the legislation enabled states to allocate TANF funds not only toward the provision of cash assistance but also toward the promotion of “job preparation, work, and marriage,” the prevention of “out-of-wedlock pregnancies,” and “the formation and maintenance of two-parent families.” Third, the introduction of TANF replaced an open-ended, federal matching funding scheme with nonindexed block grants and a mandatory Maintenance of Effort (MoE) requirement, a level of expenditures that states must commit to the program (Falk 2016a). Put differently, the federal government provides states a fixed sum of funds each year to manage their TANF programs, which states must then add to with their own resources.
The combination of these three changes provided state governments with increasing flexibility in deciding how to utilize their TANF block grants. States can effectively decide who is eligible for TANF benefits, what conditions potential beneficiaries should meet to receive benefits, and the level of benefits that a participating individual will receive. More broadly, states can decide to allocate their TANF funds to a wide array of noncash purposes. By 2016, the average state spent only 24% of its TANF budget on cash assistance, down from 56% in 1998, despite the relative stability of total TANF spending over time (Schott et al. 2018).
Explaining the Decline in Cash Assistance
What explains the decline in states' allocations of cash assistance from AFDC/TANF? Prior research detailing the decline of cash support can be grouped into three sets of potential explanations: declining need for cash assistance from TANF, declines in the participation rate among low-income households, and declining benefit generosity of TANF cash assistance. I detail these three explanations in turn.
First, prior research found that rising employment rates of single mothers (the primary target and beneficiaries of TANF support), rising educational attainment among single mothers, and/or declining single motherhood in general might contribute to the decline in TANF (Grogger and Karoly 2005; Haider et al. 2003; Haskins 2016; Haskins and Weidinger 2019; Schoeni and Blank 2000). I refer to these sets of explanations as relating to declining need for TANF cash assistance. Given the labor market gains for single mothers, the decline of cash assistance from TANF may simply represent a declining share of families in need of support. Haskins (2016:224) wrote, for example, that “an increase in work by low-income mothers” and the associated “decline in the welfare rolls” are among the “major and positive effects” of TANF's introduction.1 Similarly, state legislators from Georgia have recently credited “the improving economy” for the state's precipitous decline in TANF caseloads (Prabhu 2019).
Second, prior research has found that even among households that appear to meet the income-based eligibility requirements for TANF, participation rates are steadily declining. Parolin and Brady (2019), for example, found that around 25% of income-eligible families received cash support from TANF in 2015 compared with more than 60% of income-eligible families in 1997. Declining participation among low-income families can likely be attributed to a number of factors, including policy-imposed barriers to TANF receipt (lifetime limits, work participation requirements, strict sanctioning schemes, penalties for having a child while receiving TANF, and so on) as well as less formal barriers, such as lack of access to state public assistance offices or lack of promotion of low-income households' eligibility for TANF benefits (Danielson and Klerman 2008; Meyer and Floyd 2020; Soss et al. 2011; Soss et al. 2001; Ziliak 2015).2 Ethnographic research, for example, found evidence that some households that are presumably eligible for TANF simply do not know that the program still exists (Edin and Shaefer 2016). These more informal barriers to access can include the stigma associated with benefit receipt (Stuber and Kronebusch 2004), administrative burdens that make the application process overly onerous for low-income families (Currie 2004; Herd and Moynihan 2018), and individual cost-benefit analyses of whether the benefits are worth pursuing or maintaining. For example, a low-income family that meets the income-based eligibility standards for TANF may decide not to pursue the assistance if the benefits are low, the application process is time-consuming, or the potential for securing employment seems high.
Finally, prior work has signaled that declining benefit levels can help to explain the decline in TANF (Hoynes and MaCurdy 1994; Stanley et al. 2016). In most states, TANF benefit values are not updated for inflation and, consequently, the decline in real value each year. In all but three states, the level of TANF benefits has declined from the mid-1990s onward. Declining benefit levels, then, may be a primary source of the decline of overall cash assistance allocations.
To be sure, changes in demand for cash assistance, participation in cash assistance, and benefit levels are products of broader social and political forces. Several studies have examined, for example, how political and racial/ethnic factors are associated with spending on cash assistance (Brown 2013; Parolin 2019b; Quadagno 1994, 1998; Schram et al. 2003; Soss et al. 2008). Other studies have acknowledged that state governments may have a financial incentive to spend little on TANF cash assistance because they can then use a larger share of their TANF budgets on programs that would otherwise be funded with general state revenues (Parolin and Luigjes 2019).
This study acknowledges this important work but is more concerned with the fundamental mechanisms underlying the decline of cash support. If cash assistance from TANF is declining, it must be due to some combination of fewer families needing it, fewer needy families receiving it, or decreases in benefit levels among those receiving cash assistance. Although studies have looked individually at these components, it remains unclear how each component contributes to the aggregate decline in cash assistance. Moreover, it remains unclear the extent to which compositional and labor market changes deserve credit for the declines in TANF need, participation, and average levels of benefit receipt.
After discussing the data sources utilized to answer these questions, the remainder of this study proceeds in two analytical steps. First, I present an accounting framework to decompose the decline of cash assistance into changes in income-based need, participation, and benefit levels. Second, I apply decomposition techniques to estimate the extent to which changes in demographic and labor market characteristics can explain the decline in TANF.
Analytical Strategy
Data Source
As I present formally in the next section, accounting for the decline in cash assistance allocations from AFDC/TANF is straightforward if the product of four indicators of the U.S. population can be consistently measured over time: (1) the number of households in the population, (2) the share of those households meeting the income-based eligibility criteria for TANF (need), (3) the share of households in need participating in TANF cash assistance (participation), and (4) the mean benefit value among households receiving TANF (benefit levels). Each of these four indicators can be measured using microdata from the Annual Economic and Social Supplement (ASEC) of the Current Population Survey (CPS).
The standard CPS ASEC, however, suffers greatly from the underreporting of means-tested transfers, such as TANF (Meyer et al. 2009). Thus, I apply benefit adjustments from the Urban Institute's Transfer Income Model (TRIM3) program. In short, TRIM3 utilizes information about each individual and household in the CPS ASEC to predict their likelihood of benefit receipt as well as the value of benefits they are likely to receive. The simulations align program participation and benefits in the CPS with federal and state administrative data, taking into account individual/household data on race, ethnicity, immigrant status, marital status, household structure, state of residence, income, state-level policy rules, and more to estimate program participation and benefit levels. TRIM3 has been utilized in several recent studies on poverty (e.g., Congressional Research Service 2017; Falk et al. 2015; Parolin 2019b; Winship 2016) and is also used extensively in the recent National Academy of Sciences report on reducing child poverty (National Academy of Sciences 2019). The TRIM3-adjusted CPS ASEC sample used in this study includes all heads of households from 1993 to 2016, the three years before TANF was implemented, and all available years of TRIM3-adjusted data afterward.3
Given recent evidence that TRIM3 may overallocate some transfer benefits to lower-income households (Stevens et al. 2018), I also replicate findings using the unadjusted CPS ASEC (without TRIM3) in Figure A3 of the online appendix. The results are substantively similar. Moreover, I present evidence in Figure A2 (online appendix) that TRIM3 more appropriately tracks allocations of cash assistance from TANF relative to the unadjusted CPS ASEC.
Although administrative data on TANF benefit allocations would be ideal, only a small number of states provide administrative records that can be merged into the CPS ASEC microdata, and generally only for a small number of years. TRIM3 simulations are the next best alternative. Prior research found that TRIM3 more closely matches administrative aggregates on benefit allocations than the unadjusted CPS ASEC (Parolin 2019a). In Figures A1 and A2 (online appendix), I compare aggregate TANF cash assistance allocations from administrative records, the TRIM3-adjusted CPS ASEC, and the unadjusted CPS ASEC. As the figures show, TRIM3 tracks administrative records with respect to levels and trends in TANF benefit allocations, whereas the unadjusted CPS ASEC does not.
Measuring Income-Based Need
An added benefit of TRIM3 is that its simulation procedures estimate whether each unit meets the income eligibility threshold for TANF benefits and its likelihood of participating in TANF. I measure income-based need as whether the household meets its state's eligibility criteria for TANF cash assistance based on its income and countable assets.
In estimating whether a family unit meets the income-based eligibility criteria for TANF, TRIM3 “follows the same steps as would be followed by a caseworker, such as applying rules for noncitizens' and students' eligibility, applying the liquid assets (resource) test, computing gross income, calculating deductions to determine net income, and performing the income tests” (Wheaton and Tran 2018:24). Income-based eligibility is determined monthly and takes into account state-level variation in eligibility rules, broad-based categorical eligibility policies, and state waivers for participation among able-bodied working-age adults. Importantly, this estimation of need is based on observed characteristics from the survey data and cannot explicitly measure behavioral violations of TANF eligibility criteria, such as a failure to meet work participation requirements or eclipsing TANF lifetime limits. Note, however, that around 44% of TANF households are not subject to time limits, time-limit closures account for only around 2% to 3% of TANF exits, and most of the decline in AFDC/TANF caseloads is due to fewer entrants rather than time-limited exits (Farrell et al. 2008; Grogger et al. 2003). Thus, this measure of need should be interpreted as meeting the income and asset guidelines for benefit eligibility, but it overstates the share of households that are truly eligible for TANF cash assistance.4
Measuring Participation
TRIM3 then simulates participation among households meeting the income-based eligibility criteria. Recall that participation is the third of the four components in the decomposition framework. The TRIM3 simulations consider program participation and benefit allocation data from federal and state administrative records when assessing the likelihood that a given household within the CPS ASEC received TANF benefits. If a household meets the income-based eligibility criteria for TANF benefits and reports receiving TANF benefits, TRIM3 still considers the household to be participating. Again, the TRIM3 simulations much more closely match administrative records on benefit receipt.
Measuring Benefit Levels
Once a participation decision is established, computing the benefits that a participating household receives—the final component of the decomposition framework—is a straightforward calculation based on state policy rules and features of the household. In sum, the TRIM3 simulations of TANF cash assistance allow for a decomposition of the decline of TANF into the four components identified in the prior section: need, participation, benefit levels, and the number of households in the population.
Measuring the Contributions of Need, Participation, and Benefit Levels
The total allocation () of TANF cash assistance at a given time (t) is the product of the number of households (), the share of all households meeting the income-based needs cutoff to receive cash assistance from TANF , the share of all households in need actually receiving TANF cash assistance in the given year , and the mean benefit value among TANF recipients (). This equation simplifies to two core components: the number of TANF participants, P, and the mean benefit value among the participants, . But conceptualizing changes in TANF cash assistance allocations as changes in each of these four components allows us to disentangle the broader mechanisms contributing to the decline of cash assistance.
Thus, in year t, 30% of households in the population meet the income-based eligibility criteria for TANF. Among those 30 households meeting the needs standard, 50% actually receive TANF cash assistance. And among the 50 households receiving TANF, the mean benefit value is $50. What explains the decline in allocations from that year to the next? Clearly, it is not due to a decline in the share of households meeting the needs standard because need increased to 40%. Instead, the decline in participation—the share of income-eligible households receiving the benefit—from 50% to 30% appears to explain the decline. In fact, if the participation rate of TANF benefits remained unchanged at 50% between the two years, cash allocations in year t + 1 would have amounted to $1,050—a large increase rather than a decline.
The only difference between Eqs. (1) and (2) is that Eq. (2) includes the prior year's share of participation rate , rather than the observed year's share, into the calculation. Thus, Eq. (2) produces a counterfactual allocation of TANF cash assistance, , in which the participation rate of TANF benefits had not changed from the prior year. Using the products of Eqs. (1) and (2) then allows a straightforward computation of the contribution of the change in participation to the overall change in TANF cash allocations between the two years: .
I then repeat this process for participation, need, and benefit levels for each year from 1994 onward to provide a descriptive portrait of how changes in each component have contributed to year-to-year changes in TANF allocations as well as aggregate changes in TANF cash assistance allocations from 1993 to 2016. In other words, the decomposition is run for each possible order of changes in need, participation, and benefit levels for each year. Because the four components operate independently (a change in participation does not lead to a mechanical change in average benefit values, for example), the sums of their four respective counterfactuals in each year add up to the aggregate year-to-year change in cash assistance allocations. As such, applying Eq. (2) answers the study's first research question by indicating which of the components has contributed most to changes in TANF cash assistance allocations over time.
Can Compositional Changes Explain Changes in TANF Need, Participation, and Benefit Levels?
I next address the second research question: to what extent can changes in demographic characteristics and labor market conditions explain changes in TANF need, participation, and benefit levels? To answer this, I first apply reweighting techniques to produce a composition-consistent population of U.S. households from 1993 to 2016. I then decompose changes in need, participation, and benefit levels for each year into two components: a share that can be explained by changes in demographics and household characteristics, and a share that is not explained by such changes. I refer to the unexplained portion as the noncompositional share of the decline in TANF. I can assume (and later, empirically test) that much of the noncompositional share of the decline in TANF can be attributed to state-level policy changes (in the case of need), formal and informal barriers to TANF participation among the eligible (in the case of participation), and a decline in real benefit values (in the case of benefit levels).
To compute the composition-constant estimates, I apply a reweighting approach intrduced in DiNardo et al. (1996). In short, DiNardo et al.'s decomposition reweights the population in a given year to match the characteristics of a population in a separate year. In the context of this study, I reweight the population in each year from 1994 to 2016 to match the composition of the 1993 population, the first year of the analysis. Specifically, I reweight the sample so that all demographic and household characteristics are constant across all years. These characteristics include the age of the household head, education of the household head, sex, family structure (dummy variables for single mother, single father, female head with children, and male head with children, with households without children as reference), employment status (dummy variables for household joblessness, dual earnership, full-time status of head, and number of weeks unemployed in the prior year), race/ethnicity of household head, number of children in the household, and interactions among the family structure, education, age, and employment characteristics. I then use the revised weights to estimate counterfactual means of need, participation, and benefit levels in each year if the composition and labor market characteristics of the population had not changed from 1993 onward.
If differences in composition—such as single parenthood, household size, and employment—were the only factors explaining differences in need, then the difference between the counterfactual and observed values for 2016 would be 0. In this scenario, the change in need unexplained by compositional differences, , would likewise be 0. Using this same logic, we can calculate the unexplained (noncompositional) share of changes in need, participation, and benefit levels for each year.
Again, U represents the share of the component's decline unexplained by changes in the composition of the population. The product, , thus provides the counterfactual cash assistance allocations in 2016 if the unexplained decline (not attributable to changes in composition) in need, participation, and benefit levels were added back into the observed allotment of cash support.
Findings
Descriptive Findings
Figure 1 presents descriptive findings on trends in income-based need, participation, and benefit levels of TANF from 1993 to 2016. The share of households meeting the income-based eligibility requirements for TANF (need) declined from an estimated 7.4% of all households in 1993 to 5% of all households in 2016. Most of this decline in need occurred after the introduction of TANF: from 1998 to 2016, the share of households meeting the needs standard fell from 6.7% to 5%.
In contrast, the participation rate of TANF (share of income-eligible households participating in the program) shows a steep decline over time. In 1993, an estimated 83.3% of households meeting the income-based eligibility requirements for AFDC participated in the program. By 2016, participation among the income-eligible dropped to 25%. As Figure 1 shows, the transition from AFDC to TANF appears to have contributed to a sharp drop in participation, followed by a steady decline. Benefit levels (right axis) have also shown a notable decline over time. In 1993, the average household participating in TANF received a mean monthly benefit value of $419 (in 2014 U.S. dollars). By 2016, that amount had fallen to $289 per month—a 31% decline. The number of households in the population (not depicted) increased from around 97.3 million in 1993 to 126.5 million in 2016.
Equation (2) can now be used to observe how changes in each of need, participation, and benefit levels contributed to year-to-year changes in AFDC/TANF cash assistance spending from 1993 to 2016. Figure 2 shows the results. The diamonds in Figure 2 depict, for each year, the total change from the prior year in AFDC/TANF cash assistance allocations. The stacked black, dark gray, and light gray bars depict the total change attributable to changes in need, participation, and benefit levels, respectively. From 1993 to 1994, for example, total TANF allocations fell by about $1.5 billion. Nearly all of the $1.5 billion decline between the two years can be attributed to declining benefit levels. As the descriptive trends presented in Figure 1 reveal, benefit levels declined from around $419 to $397 in real value between these years, whereas need and participation remained mostly constant.
In subsequent years, however, changes in benefit levels were less consequential to the decline in cash assistance from AFDC/TANF relative to declines in need and participation. In the years immediately following welfare reform (1997 to 1999), for example, declines in participation contributed most substantially to the large declines in cash allocations. From 1996 to 1997, and again from 1997 to 1998, total TANF cash allocations fell by $4 billion per year, with declines in participation driving the majority of the decline. This evidence contradicts claims that rising employment rates among single mothers deserve credit for the initial decline in TANF cash assistance after welfare reform (Haskins and Weidinger 2019). Instead, policy changes that limited access to TANF cash assistance for families who met the income-based eligibility criteria were the primary drivers of decline from 1996 to 1998.
In contrast, declines in TANF allocations from 1998 to 1999, and then from 1999 to 2000, were driven primarily by declines in need, or the share of households that met the income-based eligibility criteria. From 2001 onward, the composition of cash assistance fluctuations was mixed, but changes in participation generally contributed most to annual declines. The only two periods in which TANF cash assistance allocations increased were during the early 2000s recession and during the financial crisis of 2008 to 2011.
Whereas Figure 2 shows the decomposition of year-to-year changes in TANF cash allocations by need, participation, and benefit levels, Figure 3 shows the cumulative contribution of each component to the overall decline in cash assistance. Here, the decline in participation rates (middle panel) and its effect on overall declines in cash assistance becomes more apparent. By 2016, declines in participation explain nearly $15 billion of the overall $25 billion decline in TANF cash allocations. When adjusted for the increase in the number of households in the population (which contributed to a 10.4% increase in TANF cash assistance allocations), declines in participation explain an estimated 52% of the total decline in TANF cash assistance allocations. Although declining need was particularly consequential during the initial years after TANF's implementation, its overall effects on the decline in TANF were relatively stable from 2000 onward, with the exception of the years of the financial crisis. By 2016, declines in need contributed to around $5.8 billion (21%) of the cumulative decline in TANF. Similarly, the contribution of benefit levels led to steep declines in cash assistance allocations from 1993 to 1997, but these allocations were then relatively stable from 1998 to 2016. Declines in benefit levels contributed to around $7.6 billion (27%) of the cumulative decline in TANF cash assistance by 2016.
The consequences of the financial crisis are again visible in Figure 3. Need, participation, and benefit levels each saw a slight increase around 2010—an aberration from their otherwise steady declines. Strikingly, though, those declines continued quickly as the recession faded. By 2012, all the increases in TANF cash assistance allocations during the recession had been offset by the renewed decline in eligibility and participation.
To what extent can changes in the demographic and labor market characteristics of the population explain these changes in need, participation, and generosity? Put differently, how much of the change in these three components remains unexplained by compositional changes? Applying DiNardo et al.'s (1996) reweighting techniques (described in the prior section), Table 1 shows the extent to which changes in need, participation, and benefit generosity can be explained by compositional changes in the population from 1993 to 2016.
The first set of rows in Table 1 displays the observed values of the three components in 1993 and 2016, and the difference in the values between the two years. In 1993, for example, 7.4% of households were eligible for TANF benefits, compared with 5% in 2016—a difference of 2.4 percentage points. The subsequent two rows present the value of each component in 2016 after the population is reweighted to match the composition of the 1993 population and the share of the difference that is unexplained by compositional changes. Finally, the explained portion of the change in each component is presented, including a breakdown of which demographic features, in particular, contributed to the observed change.
If the 2016 sample looked like the 1993 sample (with respect to education, employment, age, household structure, race/ethnicity, and citizenship), the estimated share of households meeting the income-based eligibility criteria (need) in 2016 would be 7.8% rather than 5%. Recall that the eligibility rate in 1993 was 7.4%. This suggests, first, that changes in the composition of the population from 1993 to 2016 have contributed meaningfully to the decline in need for TANF benefits and, second, that need would actually be higher in 2016 than in 1993 if the populations were compositionally equivalent. The results suggest that changes in family structure (a decline in single motherhood) and a rise in educational attainment contributed most to the decline in TANF need, followed closely by changes in employment. The difference between the composition-adjusted estimate in 2016 (7.8%) and the observed value in 1993 (7.4%) is 0.4 percentage points, which represents the noncompositional share of the change of TANF eligibility.
The middle column shows that if the households meeting the income-based eligibility criteria for TANF in 2016 matched the composition of such households in 1993, the estimated participation rate of TANF benefits in 2016 would increase slightly to 27.6%, not much different from the observed value of 25.2%. Thus, an estimated 55.7 percentage points of the 58.1 percentage point decline in TANF participation remains unexplained by compositional differences of households in need of TANF.
Meanwhile, benefit levels would actually fall by around $187 in 2016 if the composition of households receiving TANF benefits in 2016 matched the composition of those receiving AFDC in 1993. This is small in comparison to the overall $1,572 change in TANF benefit levels from 1993 to 2016. An estimated $1,759 decline in TANF benefit levels remains unexplained by differences in the characteristics of households receiving benefits.
To summarize, changes to family structure, education, and employment appear to fully explain the 2.4 percentage point decline in the need for TANF from 1993 to 2016. However, compositional changes fail to explain the vast majority of the decline in TANF participation and benefit levels. Instead, policy changes limiting access to benefits likely explain the decline in participation, whereas the decline in mean benefit levels among TANF recipients is likely attributable to deliberate policy decisions to cut TANF benefits or a lack of updating benefit values to inflation. In Tables A1 and A2 (online appendix), I test these claims empirically, finding that federal and state policy decisions indeed contribute to the unexplained decline in participation and benefit levels. Here, though, I focus on the consequences of the declines for the evolution of cash assistance allocations.
Following Eqs. (4) and (5), the unexplained decline in need, participation, and benefit levels can be added to the observed values in 2016 to produce a counterfactual allotment of TANF cash assistance. The final row in Table 1 provides these values. The counterfactual share of households in need would decline from 5% to 4.6%: the difference not explained by compositional changes was −0.4 percentage points. In contrast, participation would increase from 25.2% to 81% in 2016, while annual benefit generosity would increase from $3,468 to $5,227. The counterfactual cash assistance allotment is calculated as the product of the weighted number of households in the U.S. sample in 2016 (126,500,000) and the values of the three components. This adds up to around $24.8 billion—an increase of more than $19.2 billion in TANF cash assistance spending in 2016.6 Thus, by 2016, compositional changes could explain only 22% of the total decline in TANF cash assistance ($5.6 billion of the $24.8 billion decline) from 1993 to 2016. Conversely, 78% of the decline ($19.2 billion of the $24.8 billion decline) remains unexplained by compositional change. As observed before, the vast majority of the decline of cash assistance can instead be attributed to reduced accessibility and benefit levels rather than reduced need.
Figure 4 repeats this exercise for 1993 to 2016 to show the evolution of potential cash assistance spending if the unexplained portion of need, participation, and benefit levels were added into each year's TANF allocations. The black area represents the observed TANF cash assistance allocations in the given year. The gray area reflects the counterfactual increase that would occur if the unexplained decline were to be reversed. The first three panels show the change in TANF allocations if only the unexplained share of the respective component were added back in overall TANF allocations, and the final panel shows the counterfactual allocations when the unexplained share for all three are added.
Figure 4 shows that changes in need in nearly all years are explained by demographic and labor market changes, similar to the results in Table 1 when examining changes in 2016. As such, there is no “unexplained” need to be added back in, and the counterfactual TANF allocations are no greater than the observed allocations. With respect to participation, shown in the second panel, the story is far different. Reversing the unexplained decline in TANF participation would consistently lead to higher TANF cash assistance allocations. The third panel shows that the same is true, albeit to a lesser extent, for benefit levels. Finally, the fourth panel shows the effect of reversing the unexplained decline for each of the three components. In this scenario, AFDC/TANF cash assistance spending would never have dropped below $20 billion. In the midst of the recent financial crisis, TANF cash assistance would have jumped to nearly $30 billion rather than the observed $9 billion. And in 2016, as already noted, TANF spending would be $19.2 billion higher than the observed level of cash assistance spending. This counterfactual increase in spending would not require new spending appropriations from federal or state governments because the resources are less than the current combined value of the TANF block grant and required MoE spending.
Discussion
If demographic change were the only factor driving changes in cash assistance from AFDC/TANF, as opposed to policy changes that have reduced participation and benefit levels from 1993 onward, states would have spent a combined $19.2 billion more in cash assistance for low-income families in 2016. To put that amount into perspective, compare it with the level of resources needed to move all single-mother households—the primary targets and beneficiaries of TANF—out of poverty. In 2016, an estimated 26.2% of single-mother households lived in poverty, according to estimates from the Supplemental Poverty Measure (SPM). The aggregate poverty gap—the combined sum of money needed to lift all households to the poverty line—summed to $14.2 billion in 2016. Thus, the additional $19.2 billion in TANF cash assistance is more than the minimum amount necessary to lift all single-mother households out of poverty. Even with labor market responses and the realities of imperfect targeting in a redistributive cash assistance scheme, the increase in cash assistance could have a large reduction effect on poverty among single-mother households.7
Notably, such a policy shift would require no new redistributive program or allotment of federal funds. The counterfactual addition of $19.2 billion in cash assistance, combined with observed spending on cash assistance, is still less than the total sum of funds that states currently spend on all activities within the TANF program (around $31 billion in 2016). This again suggests that the declining real value of states' TANF block grants is not the most important factor in shaping declines in TANF cash assistance. However, a reallocation of TANF funds back to cash assistance would require states to pull TANF resources from other programs and services, and some of these alternative services are likely to have value for low-income families.
Table 2 presents evidence of how states tend to reallocate their TANF funds after cutting back on spending on cash assistance. From 1997 to 2014, nearly one-half of the funds pulled back from cash support were reinvested in childcare assistance.8 Thus, some low-income families who now lack cash support from TANF may be more likely than before to benefit from TANF-funded childcare assistance. If so, reverting TANF resources solely to cash assistance may be counterproductive for such families. By contrast, an estimated 40% of TANF funds pulled back from cash assistance have been reallocated toward an opaque range of other services and family-formation purposes. These other services range from funding for overnight camps, textbook subsidies for college students, scholarships for college students from well-off families, the imputed value of Girl Scouts' volunteer time, the Alternatives to Abortion Program, compulsive gambler assistance, funding for foster care, funding for family-related judicial administration, the creation of a university volleyball court, speaking fees for professional athletes, grants to nonprofit organizations, domestic violence services, and much more (Haskins and Weidinger 2019; Parolin 2019b; Wolfe 2020). Put simply, it is unlikely that spending on these alternative programs and services has the same effect on the well-being of low-income families as direct cash support does (Duncan and Magnuson 2013; National Academy of Sciences 2019; Shaefer et al. 2019).
A full shift in TANF resources toward cash assistance is not likely to be politically feasible and would require some states to redirect resources away from childcare assistance and other services. Nonetheless, the evidence suggests that a large share of TANF funding has been redirected toward programs or services that are less likely to reduce poverty. State governments could redirect this noncore TANF spending back to cash assistance to potentially make meaningful reductions in child poverty.
Conclusion
Spending on means-tested cash assistance through the AFDC/TANF program in the United States has declined by 78% in real terms from 1993 to 2016. Whereas some studies have attributed the declines in cash assistance to rising employment rates among single mothers and the decline of single motherhood more generally, others have attributed them to declining real benefit levels and the barriers that low-income families face in attempting to access cash support. This study empirically decomposes changes in cash assistance allocations into each of these components, measuring how variation in income-based need, participation, and benefit levels contributed to the observed $25 billion decline in AFDC/TANF cash assistance allocations from 1993 to 2016.
The primary findings suggest that only around one-fifth of the decline in cash assistance from AFDC/TANF can be attributed to improvements in the economic well-being of low-income families. Specifically, this study finds that the rising employment rates among single parents, shifts in the incidence of single parenthood, and changes in other compositional factors can explain only 22% (around $5.5 billion) of the decline in AFDC/TANF cash assistance allocations. Compositional changes fail to explain 78% ($19.2 billion) of the aggregate decline, indicating that most of the decline in cash assistance is not due to improving living standards or rising employment rates.
Instead, declines in the receipt of TANF cash assistance among households meeting the income-based eligibility standards (participation) contributed to more than 50% of the overall decline in cash assistance. Nearly all of the decline in participation rates remains unexplained by compositional differences in the income-eligible households. Instead, federal and state policy decisions designed to inhibit access to cash assistance have led to a sharp decline in participation among families who otherwise meet the income-based eligibility cutoffs (see Table A1, online appendix). Had the participation rate of AFDC/TANF benefits remained constant from 1993 onward, TANF allocations in 2016 would have amounted to $15 billion more than the observed value. Declines in TANF cash assistance benefit levels explain about 27% of the overall decline in AFDC/TANF allocations. This decline is instead largely due to the nonindexation of TANF benefit values in most states (see Table A2, online appendix). Had benefit levels remained constant, cash assistance spending from TANF would have increased by about $7.6 billion in 2016.
That declining participation and benefit levels contribute more to the decline in TANF than do changes in the living standards of low-income families should prompt concern as to whether TANF has worked as policymakers intended and whether the program has inhibited potential reductions in child poverty. As discussed in the Introduction, a vast body of research has demonstrated that greater investment in cash assistance for families contributes to lower child poverty rates. This study shows, however, that most of the decline of means-tested cash assistance through AFDC/TANF—around $19.2 billion worth—is not due to reduced demand for cash assistance. Were this $19.2 billion to be reinvested into cash assistance in 2016, meaningful progress could be made in reducing levels of poverty among single-mother households. Specifically, $19.2 billion is more than enough to bring all single-mother households above the Supplemental Poverty Measure poverty line. Such an increase in cash support would not require a new redistributive program, given that all of the funds are already built into the TANF program, although it would require reallocating TANF funds from other family-related investments back to cash assistance.
These findings also cast skepticism on claims that the declining real value of states' TANF block grants is to blame for declines in cash assistance spending. The counterfactual $19.2 billion increase in cash support, combined with current levels of spending on TANF cash assistance, is still less than the $31 billion that states spent on all activities within the TANF program in 2016. This is in part due to increases in state MoE spending, which compensated for the declining real value of the TANF block grant. Moreover, a look at states' TANF spending priorities does not support the claim that declining block grant values are the cause of declines in spending on TANF cash support. Consider that more than 10 states spent less than 10% of their TANF budgets on cash assistance in 2016. For the size of block grants to be a primary constraint on cash assistance, states would presumably need to be using a relatively high share of their current TANF budgets on cash support. That is not the case.
In closing, several limitations of this study should be acknowledged. First, this study's framework for decomposing changes in cash assistance into changes in need, participation, and benefit generosity, and the number of households partially assumes independence among the four components. In other words, the framework assumes that differences in the share of households meeting the income-based eligibility cutoff for TANF will not affect differences in the share of such households that actually collect TANF benefits, and that neither will affect the number of households in the population. If the assumption of independence were violated, the utility of the framework would be weakened. More generally, the models and counterfactuals presented in this study are static and do not account for behavioral responses. Results should be interpreted accordingly.
Moreover, low-income families that do not receive cash assistance support from TANF still may receive TANF-funded support for childcare, transportation costs, or a range of services from compulsive gambler assistance to the Healthy Fatherhood initiative. It is not possible to measure or quantify access to such services in this analysis. Nonetheless, this study maintains that access to other TANF-funded services is important but is generally no substitute for direct cash assistance when it comes to immediately increasing the economic well-being of jobless low-income families (Duncan and Magnuson 2013; McLaughlin and Rank 2018; National Academy of Sciences 2019).
Moving forward, scholars can apply this study's decomposition framework to understand changes in other social programs, such as benefits from the SNAP or EITC programs. As this study demonstrates, understanding the relative contributions of policy changes compared with compositional changes in shaping trends in social assistance is pertinent for understanding the evolution of the American safety net and its consequences for low-income households.

Notes
Haskins (2016) also acknowledged that the decline of cash assistance might have contributed to a deepening of poverty among disconnected families and those who lack access to stable employment.
A limitation of this analysis is that it is not possible within the data to identify families who have received TANF benefits for the maximum allowed duration and, thus, who are no longer eligible for cash assistance. These families are identified as having incomes below the eligibility standards even if they are not technically eligible for more cash assistance.
I designate the lead earner in each household as the head. If two adults in the household earn the same amount, I select the oldest of the equal earners as the head. If the earners are the same age, I randomize selection of the head among the same-aged equal earners. When measuring trends in household receipt of TANF, precise selection of the head is not consequential because benefit levels are measured at the household level.
TRIM3 uses income from rents, royalties, interest, dividends, estates, and trusts as a measure of asset income. Many states link their TANF eligibility criteria to the federal poverty guidelines, which are updated for inflation. As such, eligibility cutoffs do not, on average, decline in real value at the same rate as maximum TANF benefit levels.
When estimating the unexplained share of changes in TANF eligibility, I reweight the entire population to match the 1993 composition. For the unexplained share of changes in participation among the eligible (participation), I reweight the given year’s sample to match the composition of households that were eligible in 1993. And for the unexplained share in benefit levels, I reweight the given year’s sample to match the composition of the participating households in 1993.
These figures are based on the TRIM3 estimates of cash assistance allocations in each year within the CPS ASEC. TRIM3 estimates of benefit allocations are slightly lower than administrative records, as shown in Figure A1 (online appendix), but are much higher and more accurate than estimates from the unadjusted CPS ASEC.
To understand why such an increase in TANF spending could achieve the elimination of deep poverty among single-mother households in 2016 yet comparable levels of spending did not achieve large reductions in deep poverty in the mid-1990s, consider that non-TANF social transfers have risen considerably from the mid-1990s onward. In particular, EITC and SNAP expansions have kept the share of household income composed of transfer benefits relatively stable over time despite the decline in TANF. Adding the counterfactual increase in TANF allocations thus has a greater potential poverty-reduction effect in 2016 relative to the years before EITC and SNAP expansions.
TANF reporting categories were changed after 2014, making it difficult to compare how changes in spending prior to 2014 compare with those after 2014. This explains the timeframe of the analysis.
