Small Area Health Insurance Estimates
The U.S. Census Bureau's Small Area Health Insurance Estimates (SAHIE) program produces estimates of health insurance coverage for states and all counties.
Data Years Available:
In July 2005, SAHIE released the first nation-wide set of county-level estimates on the number of people without health insurance coverage for all ages and those under 18 years old. In July 2010, SAHIE released 2007 estimates of health insurance coverage.
Mode of Collection:
SAHIE presents estimates of persons with no health insurance by age group, sex, poverty level, and for more recent years, race and ethnicity.
The SAHIE program models health insurance coverage by combining survey data with population estimates and administrative records. The estimates are based on data from the following sources: •The Annual Social and Economic Supplement (ASEC) of the Current Population Survey (CPS); •Demographic population estimates; •Aggregated federal tax returns; •Participation records for the Supplemental Nutrition Assistance Program (SNAP), formerly known as the Food Stamp program; •County Business Patterns; •Medicaid and Children's Health Insurance Program (CHIP) participation records; and •Census 2000.
