Temporal trends in the uninsured rate by state Medicaid expansion status. There was generally a slowly decreasing uninsured rate in early Medicaid expansion states until 2013, with a smaller gap of the uninsured rate between early and not early expansion states in 2013 compared with the gap in 2006. The elevated uninsured rates in 2009 and 2010 may be secondary to the great recession. Beginning in 2014, with the initiation of the larger scale Medicaid expansions, early Medicaid expansion states had a larger decrease in the uninsured rate than the other groups of states, including the group of all states that expanded in 2014.
