Survey estimates of public health insurance program enrollment tend to be lower than those compiled from administrative enrollment data for those same programs, a discordance which is particularly apparent for Medicaid. The crude Medicaid undercount in the Current Population Survey’s Annual Social and Economic Supplement (CPS), the most prominently used survey for policy research that measures health insurance coverage, was 32 percent in both 2000 and 2001. Given the important uses of the CPS data, improved understanding of the undercount in the CPS is crucial.
