Abstract
Beginning in June 2013, the Urban Institute's Health Reform Monitoring Survey (HRMS), which was designed to provide early feedback on implementation of the Affordable Care Act (ACA), has been tracking changes in health insurance coverage and other outcomes for children under the ACA. In contrast to adults, uninsured rates for children had been declining in the decade before the ACA's passage, largely because of the expansion of public coverage (Medicaid and the Children's Health Insurance Program) which is substantially generous and draws high participation among children. Estimates derived from HRMS children's supplement suggest that uninsured rates for children had not changed by June 2014 from their pre-ACA levels, though there are reasons to expect that children's coverage will grow in future years.
