TLDR
Findings show that the standard error estimates derived from the public use CPS data perform poorly compared with the survey design-based estimatesderived from restricted internal data, and that the generalized variance parameters currently used by the U.S. Census Bureau in its ASEC reports and funding formula inputs perform erratically.Abstract:
Statistical analysis of the Current Population Survey's Annual Social and Economic Supplement is used widely in health services research. However, the statistical evidence cited from the Current Population Survey (CPS) is not always consistent because researchers use a variety of methods to produce standard errors that are fundamental to significance tests. This analysis examines the 2002 Annual Social and Economic Supplement's (ASEC) estimates of national and state average income, national and state poverty rates, and national and state health insurance coverage rates. Findings show that the standard error estimates derived from the public use CPS data perform poorly compared with the survey design-based estimates derived from restricted internal data, and that the generalized variance parameters currently used by the U.S. Census Bureau in its ASEC reports and funding formula inputs perform erratically. Because the majority of published research (both by academics and Census Bureau analysts) does not mak...read more

Income, Poverty, and Health Insurance Coverage in the United States: 2004
TL;DR: The US Census Bureau report highlights the increasing poverty and racial inequality in America as mentioned in this paper, showing that the poverty rate increased from 12.5 percent in 2003 to 12.7 percent in 2004; 1.1 million more people -a total of 37 million -lived in poverty in 2004.

Understanding the Long-Run Decline in Interstate Migration
Greg Kaplan,Sam Schulhofer-Wohl +1 more
TL;DR: The authors argue that migration fell because of a decline in the geographic specificity of returns to occupations, together with an increase in workers' ability to learn about other locations before moving, which is consistent with cross-sectional and time-series evidence.

An examination of the Medicaid undercount in the current population survey: preliminary results from record linking.
TL;DR: The CPS is widely used for health policy analysis but is a poor measure of Medicaid enrollment at any time during the year because many people who are enrolled in Medicaid fail to report it and may be incorrectly coded as being uninsured.

TL;DR: Lohr's SAMPLING: DESIGN and ANALYSIS, 2ND EDITION as mentioned in this paper provides guidance on how to tell when a sample is valid or not, and how to design and analyze many different forms of sample surveys.

Variance estimation for complex surveys using replication techniques
TL;DR: The use of the jackknife, balanced repeated replication, and the bootstrap techniques for estimating sampling variances and the use of such variance estimates in drawing inferences from survey data is discussed.

A Simple Method for Approximating the Variance of a Complicated Estimate
TL;DR: In this paper, the authors show the useful results which can be obtained by simply reversing the order between selection units and component variables in this linear expression, assuming that the samples are large enough to justify using the Taylor approximation.
