The Census Bureau produces estimates of health insurance coverage in the United States at various levels of geography.

National Data

National estimates of coverage based on the Current Population Survey are released along with the official poverty estimates.  Because of the redesign of the Current Population Survey’s health insurance questionnaire, starting with 2013 CPS estimates of health insurance coverage are not directly comparable to estimates from prior years.

The Census Bureau now provides comparable annual estimates drawn from the ACS.  Tables and figures provide information on insurance coverage and the uninsured with demographic and socioeconomic breakdowns. 

Frequency and Timespan: CPS comparable annual data available from 1999 (for health insurance) to 2012; from 2013 onward estimates are not directly comparable to prior years.  ACS estimates from 2008 onward

Geographic Level of Coverage: National with some regional breakdowns

Publications and Tables are available online
