State Data: What Has Happened to Health Coverage and Financing Under the Affordable Care Act?

As Congress presses forward with efforts to repeal and replace the Affordable Care Act, a new interactive map from the Kaiser Family Foundation provides a window into the changes in health insurance coverage and financing in each state under the 7-year-old law. The ACA increased enrollment in health insurance by expanding Medicaid, offering tax credits to low- and middle-income marketplace enrollees and reforming insurance market rules concerning coverage for people with pre-existing health conditions. Map users can scroll over each state to see detailed breakdown of ACA-related data, including:

  • The number of people enrolled in plans in the ACA marketplace, the number of enrollees receiving advance premium tax credits to help them buy insurance, and the total amount of money in the form of such credits received by marketplace enrollees in the state;
  • The number of enrollees in Medicaid, with a break out of the number of Medicaid expansion enrollees in the 31 expansion states and Washington D.C., as well as total federal Medicaid spending and Medicaid expansion spending in the state;
  • The reduction in the number of people without health coverage in each state between 2013 and 2015, as well as the estimated number of people in the state with pre-existing health conditions.

The map also shows the political party affiliations of U.S. senators in each state. Replacement legislation under consideration in Congress has the potential to affect every state’s Medicaid program and individual health insurance market.

Also, available in a separate interactive are our newly updated state Medicaid fact sheets, which now include more recent state data on opioid deaths, HIV diagnoses, Medicaid enrollment and Medicaid spending.
