Geographic Concentration of the Uninsured
This analysis was conducted by the State Health Access Data Assistance Center (SHADAC) to estimate the geographic concentration of the uninsured across U.S. counties. The estimates are from the 2011 Small Area Health Insurance Estimates (SAHIE) program at the U.S. Census Bureau. The SAHIE program models health insurance coverage by combining survey estimates with administrative records, population estimates, and the decennial census. This method produces annual estimates for all counties and includes a limited set of demographic features. The advantage of using the SAHIE is that it is the only source of annual estimates of number of uninsured for all counties.
