Our analysis finds that,after increasing substantially (by 64% to 17.4 million people in 2015) following implementation of the ACA, enrollment in the individual market remained relatively unchanged in 2016 (at 17.0 million) then declined by 12% to 15.2 million in 2017. Enrollment has continued to topple in early 2018: first quarter enrollment has declined by 12% in 2018 compared to the first quarter of 2017 . Much of this decline in overall individual market enrollment was concentrated in the off-exchange market, or where enrollees are not eligible for federal premium subsidies and therefore were not cushioned from the meaningful premium increases in 2017 and 2018. Despite the recent decline in overall individual market enrollment,there are still 14.4 million people enrolled as of the first quarter of 2018, compared to 10.6 million people in 2013.
