To assess the quality of the Current Population Survey's (CPS) Child Health Insurance Program (CHIP) data.
Linked 2000-2004 Medicaid Statistical Information System (MSIS) and the 2001-2004 CPS.
Centers for Medicare & Medicaid Services provided the Census Bureau with its MSIS file. The Census Bureau linked the MSIS to the CPS data within its secure data analysis facilities.
We compared responses to the CPS health insurance items with Medicaid and CHIP status according to the MSIS.
CHIP reporting in the CPS is unreliable. Only 10-30 percent of those with CHIP (but not Medicaid) report this type of coverage in the CPS. Many with CHIP report Medicaid coverage, so the reporting error for a Medicaid-CHIP composite is smaller, but still substantial.
The quality of the CPS CHIP information renders it effectively unusable for health policy analysis. Analysts should consider using a Medicaid-CHIP composite for CPS-based analyses.
评估当前人口调查（CPS）中儿童健康保险计划（CHIP）数据的质量。
2000 - 2004年医疗补助统计信息系统（MSIS）与2001 - 2004年CPS的关联数据。
医疗保险和医疗补助服务中心向人口普查局提供其MSIS文件。人口普查局在其安全的数据分析设施中将MSIS与CPS数据相链接。
我们根据MSIS将CPS健康保险项目的回答与医疗补助和CHIP状态进行了比较。
CPS中CHIP的报告不可靠。在有CHIP（但没有医疗补助）的人群中，只有10% - 30%的人在CPS中报告了这种保险类型。许多有CHIP的人报告了医疗补助保险，所以医疗补助 - CHIP综合报告的误差较小，但仍然很大。
CPS中CHIP信息的质量使其实际上无法用于健康政策分析。分析人员在基于CPS的分析中应考虑使用医疗补助 - CHIP综合数据。
