The Affordable Care Act’s Coverage Impacts in the Trump Era

Contributed to by past PISC trainee Ben Ukert, PhD, this study investigated how the impact of the Affordable Care Act (ACA) on insurance coverage changed during the Trump administration, particularly between 2017 and 2019. After analyzing the 2011-2019 waves of the American Community Survey, the study found that coverage gains from the ACA's national components fell from 5% in 2016 to 3.6% in 2019, while the the coverage gains from Medicaid expansion increased in 2017 before returning to the 2016 levels in 2019. The authors conclude that, "the net effect of the ACA in expansion states is a combination of these trends, with coverage gains falling from 10.8 percentage points in 2016 to 9.6 percentage points in 2019."
