Enrollment in the health insurance market in the U.S. 2015-2018, by exchange type
In 2018, some 8.6 million Americans were enrolled in an on-exchange (subsidized) individual health insurance plan, compared to 8 million in 2015. The individual health insurance market in the U.S. has grown after the enforcement of the Affordable Care Act (ACA) subsidies and prohibition of discrimination based on pre-existing conditions. However the increases in enrollment were offset by reductions, due to some individuals not receiving subsidies. In 2019, the ACA's individual mandate penalty was repealed, which can cause enrollment to drop further.
