Published: 19 January 2017
...Jeffrey Napierala; Nancy Denton Abstract The American Community Survey (ACS) provides valuable, timely population estimates but with increased levels of sampling error. Although the margin of error is included with aggregate estimates, it has not been incorporated into segregation indexes...

Demography (1999) 36 (1): 121–134.
Published: 01 February 1999
.... Interpretations about the purpose and meaning of the census, about commitment to the task, and about connection to government, singly and together with literacy skills (e.g., reading and general literacy competence), were associated with errors that are not detectable by evaluative methodologies used regularly...
Journal Article
Demography (2015) 52 (4): 1345–1355.
Published: 25 June 2015
...Erin R. Hamilton; Robin Savinar Abstract We examine the nature and degree of two sources of error in data on migration from Mexico to the United States in Mexican household-based surveys: (1) sampling error that results when whole households migrate and no one is left behind to report...
Journal Article
Demography (1976) 13 (2): 273–286.
Published: 01 May 1976
...Barbara A. Bailar Abstract Often the reliability of survey data is examined only in relationship to sampling variances, excluding many other potential sources of error. If the sampling variance dominates the mean-square error, then few mistakes result by considering sampling variance only; however...

Fig. 2 Plot of the square root of the mean squared error of states’ detention rates by year (panel a) and boxplots of state detention rates by region and year (panel b) for the period 1999–2011. Each boxplot captures the distribution of detention rates for all states in that region and year More

Fig. 3 Out-of-sample error rate, with 95% confidence intervals calculated from bootstrapping with 100 repetitions. Testing samples are used for prediction. IBS = integrated Brier score. Cox-PH 2way = Cox proportional hazard two-way interaction model. Cox-PH 2way select = Cox proportional hazard More

Fig. 3 Model fit measure or root mean squared error (Eq. ( 5 )) in response to varying ability parameters (ρ and ϕ in panel a), and varying readiness parameters (σ and β in panel b). Lower values indicate better fit between simulated and UN SRB estimates More

Fig. 3 Genetic correlations for logged migration distance. Circles and error bars indicate genetic correlation estimates and standard errors. Correlations significant at the 5% level after Bonferroni correction are highlighted as open circles. ADHD = attention-deficit/hyperactivity disorder. LDL More

Fig. 2 Migration patterns and EA PGI. Colored bars and error bars represent estimated mean PGIs and their robust standard errors. The first 20 principal components are controlled. Capital letters indicate the six-category migration groups: (A) moved from a coal mining to a non–coal mining place More

Fig. 4 Median prediction error by sample fraction, with 50 samples for each sample fraction. For each sample, the median is calculated across all ages and all mortality schedules in each sample category (in-sample and out-of-sample). Whiskers extend to 10 % and 90 % quantiles. More

Fig. 6 Marital status of men and mortality. Error bars are 95% confidence intervals. The estimates shown across the four panels are from the same model, and the common reference category is men in first monogamous marriages who have not been widowed. Estimates are based on Models 8 and 9. More

Fig. 4 Sources of error in FBH data. Date displacement refers to events reported to have occurred earlier/later than recorded by the HDSS, leading to erroneous exclusion/inclusion from the reference period. Age understatement refers to errors resulting from the fact that a respondent More

Fig. 1 Absolute error (births/woman) in TFR over alternative methods and data sets. Solid dots are at median error for each method and data set. Horizontal bars extend from the 10th to 90th percentile of error. Numbers in parentheses indicate the count of schedules for which it is possible More

...D. Paul Sullins Abstract Because of classification errors reported by the National Center for Health Statistics, an estimated 42 % of the same-sex married partners in the sample for this study are misclassified different-sex married partners, thus calling into question findings regarding same-sex...

... errors but not age and date errors. Overall, SSH data led to a 20 % underestimate of 45 q 15 relative to HDSS data. Our study suggests new quality improvement strategies for SSH data and demonstrates the potential use of HDSS data for the validation of “unconventional” demographic techniques. Third...

...Stanley K. Smith; Terry Sincich Abstract Many studies have found that population forecast errors generally increase with the length of the forecast horizon, but none have examined this relationship in detail. Do errors grow linearly, exponentially, or in some other manner as the forecast horizon...
