Medicaid Undercount: Phase II Research Results
Medicaid Undercount: Phase II Research Results
Executive Summary
Survey estimates of public health insurance program enrollment tend to be lower than those compiled from administrative record data. This discordance is particularly apparent for Medicaid and this has become known as the “Medicaid undercount”. Many causes have been postulated for the undercount with varying potential implications for policy research and resulting policy recommendations. The crude Medicaid undercount in the Current Population Survey’s Annual Social and Economic Supplement (CPS ASEC), the most prominently used survey for policy research that measures health insurance coverage, was about 32 percent for both 2000 and 2001. In order to investigate reasons for the undercount, a team of researchers designed the analysis described in this report.
