Health Insurance Historical Tables - HHI Series

The Current Population Survey Annual Social and Economic Supplement (CPS ASEC) provides the Census Bureau's most timely and accurate national data on health insurance coverage by type with detailed information on income and employment.  

The CPS ASEC time series goes back to 1987. Making comparisons over time requires caution, since annual estimates reflect survey improvements, including (a) the addition of a verification question in 1999, (b) redesign of the questionnaire in 2014, and (c) improvements to the CPS ASEC processing system in 2018.  

The HHI series provides estimates of health insurance coverage from 2017 forward. 

In addition to the estimates from the CPS, the Census Bureau produces annual estimates of health insurance coverage from the American Community Survey (ACS). Due to its large sample size, the ACS provides estimates at many levels of geography, including state-level estimates. To examine changes in health insurance over a longer time period (2008-2022), see the HIC ACS tables.
