This analysis provides data about changes in the uninsured between 2013 and 2015 by Congressional District and a range of demographic characteristics (race, age, income, citizenship, etc.). These data show the impact of the ACA, which was implemented in 2014, on the uninsured.

A Note about Congressional Districts
The data used for this analysis align with Congressional District borders from the 114th Congress, which are unchanged from the 113th Congress, so geographies are consistent between the two time periods analyzed.
About the American Community Survey
The estimates in this analysis come from the American Community Survey (ACS) via the U.S. Census Bureau's American FactFinder (AFF) tool.
The ACS is a household survey that began in 2005 and produces annually updated data on a variety of population characteristics, including health insurance coverage. In total, the ACS surveys approximately three million US households each year.
An important feature of the ACS is that it includes a large enough sample for state‐level and sub‐state estimates such as the estimates in this analysis.
