OBJECTIVE
To create a consistent time series to understand coverage trends by harmonizing 20 years of insurance coverage estimates from the Current Population Survey (CPS) that are an available public resource.
DATA SOURCE
1990-2009 CPS Annual Social and Economic Supplement data.
STUDY DESIGN
CPS data are enhanced to account for methodological and conceptual changes in health insurance measurement and population control totals.
PRINCIPAL FINDINGS
The enhancements to the CPS result in an approximately 1 percent reduction in uninsurance rates. Reductions vary over time and by age group. Changes over the last two decades differ slightly using the two data sources. For example, the enhanced data show a greater erosion of private coverage.
CONCLUSION
The enhanced data provide the most consistent measure of health insurance coverage over the past two decades.
目的
通过协调可利用的公共资源——来自当前人口调查（CPS）的 20 年保险覆盖估计，创建一个一致的时间序列，以了解覆盖范围的趋势。
资料来源
1990-2009 年 CPS 年度社会经济补充数据。
研究设计
对 CPS 数据进行增强，以说明医疗保险测量和人口控制总数方面的方法和概念变化。
主要发现
对 CPS 的增强导致未保险率降低约 1%。减少幅度随时间和年龄组而异。过去二十年来的变化使用两种数据源略有不同。例如，增强的数据显示私人保险的侵蚀更大。
结论
增强的数据提供了过去二十年来医疗保险覆盖范围最一致的衡量标准。
