2008 - 2020 Small Area Health Insurance Estimates (SAHIE) using the American Community Survey (ACS)

Starting with the 2008 SAHIE estimates, the SAHIE program updated its methodology to incorporate the estimates of health insurance coverage from the American Community Survey (ACS). The incorporation of the ACS into the modeling procedures has allowed for more detailed income group data as well as a higher level of precision in the estimates.
