Abstract:
|
Previous research has shown that the CPS ASEC under-counted Medicaid participation and over-counted the number of uninsured. This study examines the extent of an undercount of Medicaid participants and the subsequent impact on the percent uninsured. The Medicaid Statistical Information System (MSIS) is an administrative database for the Medicaid program. A field test of the American Community Survey that tested the overall quality of the new questions on health insurance. The MSIS database is linked to the persons in the ACS field test. The linked data will be examined at the household and person level for the types of health insurance reported and conflicts in what the survey and MSIS reports. This research shows that the count of Medicaid participants is underestimated and the uninsured rate should be lower, given the administrative records are without error.
