Figure 2. Population of adults aged 18 to 64 years by Medicaid expansion status among 3 state groups (above national average, equivalent to national average, below national average) categorized by estimated state prevalence of lack of health insurance in relation to the national average, 2013 Behavioral Risk Factor Surveillance System (http://www.cdc.gov/brfss/). Fifteen states were above the national average (6 with Medicaid expansion and 9 without); 12 states were equivalent to the national average (8 with Medicaid expansion and 4 without), and 24 states were below the national average (17 with Medicaid expansion and 7 without).

| Live in state with expanded Medicaid | 11.8 | 43.6 | 55.6 |
| Live in state without expanded Medicaid | 46.5 | 10.7 | 15.0 |
