本文研究了收入和计划参与调查（SIPP）中报告的医疗补助覆盖范围的准确性，使用加州州的行政记录。总的来说，我们估计SIPP低估了加州人口的医疗补助覆盖率约10%。正确报告医疗补助实际覆盖范围的概率约为85%，对于低收入儿童甚至更高。没有被医疗补助覆盖的人错误地报告他们被覆盖的概率对于整个人口来说大约是1.3%，但对于低收入儿童来说更高（高达7%）。
This article studies the accuracy of reported Medicaid coverage in the Survey of Income and Program Participation (SIPP) using administrative records from the State of California. Overall, we estimate that the SIPP underestimates Medicaid coverage in the California population by about 10%. The probability of correctly reporting coverage for those actually covered by Medicaid is around 85%, and is even higher for low-income children. The probability that people who are not covered by Medicaid incorrectly report that they are covered is about 1.3% for the population as a whole, but is higher (up to 7%) for low-income children.
