This Data Snapshot provides 50-state data on Medicaid monthly enrollment trends, adding June 2013 data. Overall, Medicaid enrollment growth continued to slow to the lowest rate since the start of the Great Recession as the economic conditions continued to slowly improve. While enrollment growth rates have been trending downward as economic conditions continue to slowly improve, enrollment growth is expected to increase significantly as states implement the ACA. Regardless of whether states decide to implement the Medicaid expansion or not, enrollment is anticipated to grow on average across all states due to new streamlined eligibility and enrollment processes as well as outreach for new coverage. This report provides baseline data for understanding the impact of the ACA eligibility and enrollment policies on enrollment growth across states.
