Health Insurance Historical Tables - HIA Series

The 2005 and 2006 Current Population Survey (CPS) Annual Social and Economic Supplement (ASEC) data were revised in March 2007 to improve the consistency of estimates for the insured and uninsured as part of ongoing efforts to improve the quality of Census Bureau data.  Because the data after the revision is not consistent with earlier data, the Census Bureau introduced a new historical series (HIA-1 to HIA-8) and discontinued the original series.  The data for 1999 to 2003 presented in these tables (from ASEC’s 2000 to 2004) were revised using an approximation method for consistency with the revision to the 2004 and 2005 estimates (2005 and 2006 ASEC’s).  Please see the link below for more information on the revised CPS ASEC health insurance data.


  1. Includes Tricare, Veterans Administration, and military health care.
  2. Estimates reflect the results of follow-up verification questions and of Census 2000 based population controls.
  3. Implementation of a 28,000 household sample expansion.
  4. These estimates from the 2005 ASEC were revised based on improvements to the algorithm that assigned coverage to dependents, and there was an adjustment to the weights.
  5. The 2003 CPS asked respondents to choose one or more races. White alone refers to people who reported White and did not report any other race category. The use of this single-race population does not imply that it is the preferred method of presenting or analyzing data. The Census Bureau uses a variety of approaches. Information on people who reported more than one race, such as "White and American Indian and Alaska Native" or "Asian and Black or African American," is available from Census 2000 through American FactFinder. About 2.6 percent of people reported more than one race in 2000.
  6.  The 2001 CPS and earlier years asked respondents to report only one race. The reference groups for these years are: White, White not Hispanic, Black, and Asian and Pacific Islander.
  7. Black alone refers to people who reported Black or African American and did not report any other race category.
  8. Asian alone refers to people who reported Asian and did not report any other race category.
  9.  Because Hispanics may be of any race, data in this report for Hispanics overlap with data for racial groups. Being Hispanic was reported by 11.8 percent of White householders who reported only one race; 2.7 percent of Black householders who reported only one race; 26.5 percent of American Indian and Alaska Native householders who reported only one race; and 10.0 percent of Native Hawaiian and Other Pacific Islander householders who reported only one race. Data users should exercise caution when interpreting aggregate results for the Hispanic population because this population consists of many distinct groups that differ in socio-economic characteristics, culture, and recency of immigration. Data were first collected for Hispanics in 1972.
