...Jeremy Pais Abstract Cumulative structural disadvantage theory posits two major sources of endogenous selection in shaping racial health disparities: a race-based version of the theory anticipates a racially distinct selection process, whereas a social class-based version anticipates a racially...

... heterogeneity. Information is pooled across neighboring regions and smoothed over time and age. To make predictions more robust and address the issue of model selection, a Bayesian version of stacking is considered using leave-future-out validation. I apply this method to forecast mortality rates for 96 regions...

... changes in fertility, mortality, and migration. However, doing so requires more than 100 years of historical data, meaning that such analyses are possible only in a select few populations. In this research note, we propose an adapted version of the variable- r model to measure contributions...

... countries never investigated the significance of large differences in birth and death rates across societies. The strong demographic components of life-cycle saving analysis are here the center of focus. Illustrative general numerical applications of a modified version of the life-cycle approach suggest...

...John C. Hudson Abstract A version of the Lotka-Volterra interaction model is adapted to describe population growth and migration processes in a two-region system. The regions are identified as a metropolis and its non-metropolitan hinterland. Several conditions on growth and migration regimes...

... cycles,” in births. Frauenthal and Swick recently reestimated a continuous-age version of Lee’s basic cohort model with U.S. series and, contrary to Lee’s original findings, concluded that “limit cycles oscillations have been occurring in U.S. births.” This article disputes their conclusion, ascribing...

... are treated as hierarchical and thus this method is conceptually different from the decomposition methods of Kitagawa (1955) and Das Gupta (1978), in which two factors are treated as symmetrical. Our method is shown to be a balanced version of the Cho-Retherford (1973) decomposition method. Analyses...

... migration. This report presents a migration projection technique compatible with these constraints. A simplified version of Pittenger's model is used, where future migration patterns are automatically assigned from characteristics of historical patterns. A comparative test of age pattern accuracy for 1970...

... were a cubic spline, the Hadwiger and Coale-Trussell functions, the gamma and beta densities, two versions of a polynomial, and two of Brass's relational procedures, as well as the Gompertz curve. The spline function fitted all curves far better than any of the others. The Coale-Trussell procedure...

... version of life expectancy. That is, the distribution of lifespans of the people alive at a single moment is a self-weighted distribution of cohort lifespans, such that longer lifespans have proportionally greater representation. One implication is that if death rates are unchanging, the average lifespan...

... States. We use the harmonized version of the Health and Retirement Survey data and define the health status in terms of activities of daily living. Our results suggest that the female advantage in cohort survival is partly compensated by women's lower cohort-specific health levels. At older ages, however...

... in an unprecedented rise in both duration and magnitude. I consider the role of the illicit opioid crisis in driving this mental health crisis. In August 2010, an abuse-deterrent version of OxyContin was introduced and the original formulation was removed from the market, leading to a shift to illicit opioids...

... applications of the cohort-component method with the accuracy of projections that were derived from a simpler, less data-intensive version of the method. We found that age-group error patterns are different for national projections than for subnational projections; that errors are substantially larger for some...

... and generally receive similar returns to years of schooling completed. Immigrants also receive substantial returns to acculturation, measured as age at arrival and English language skill. These results cast doubt on the strong version of segmented labor market theory, in which low-skill immigrants...

...Brian L. Rostron; John R. Wilmoth Abstract Declines in mortality rates for females at older ages in some developed countries, including the United States, have slowed in recent decades even as decreases have steadily continued in some other countries. This study presents a modified version...

...Matheu Kaneshiro Abstract The quality of the decennial census of the United States is compromised by population undercount, which often misses immigrants and racial/ethnic minorities, thereby diminishing federal resources allocated to such groups. Using a modified version of demographic analysis...
