Purpose To evaluate the impact of the Affordable Care Act's (ACA) dependent coverage mandate on insurance coverage among young adults in metropolitan and nonmetropolitan areas. Methods A cross‐sectional analysis was conducted using data from 2006‐2009 and 2011 waves of the Medical Expenditure Panel Survey. A difference‐in‐difference analysis was used to compare changes in full‐year private health insurance coverage among young adults aged 19‐25 years with an older cohort aged 27‐34 years. Separate regressions were estimated for individuals in metropolitan and nonmetropolitan areas and were tested for a differential impact by area of residence. Findings Full‐year private health insurance coverage significantly increased by 9.2 percentage points for young adults compared to the older cohort after the ACA mandate ( P = .00). When stratifying the regression model by residence area, insurance coverage among young adults significantly increased by 9.0 percentage points in metropolitan areas ( P = .00) and 10.1 percentage points in nonmetropolitan areas ( P = .03). These changes were not significantly different from each other ( P = .82), which suggests the ACA mandate's effects were not statistically different by area of residence. Conclusions Although young adults in metropolitan and nonmetropolitan areas experienced increased access to private health insurance following the ACA's dependent coverage mandate, it did not appear to directly impact rural‐urban disparities in health insurance coverage. Despite residents in both areas gaining insurance coverage, over one‐third of young adults still lacked access to full‐year health insurance coverage.
