evidence: In 2018, 58 percent of uninsured adults had incomes below 200 percent of the federal poverty level ($24,120 for an individual and $49,200 for a family of four). Across age groups, young adults ages 19 to 34 made up the largest share of the uninsured. More than one-third of the uninsured were Latino even though Latinos make up 18 percent of the working-age adult population (Table 1). We examined the remaining uninsured by income status to determine whether they might be eligible for subsidized coverage. The ACA provides subsidized insurance through two sources: Medicaid for adults who earn less than 138 percent of poverty ($16,643 for an individual or $33,948 for a family of four) in states that expanded Medicaid, and subsidized plans in the ACA marketplaces for those who earn up to 400 percent of poverty ($48,240 for an individual and $98,400 for a family of four). [...] Nearly half (47%) of uninsured adults in 2018 had incomes that may make them eligible for either expanded Medicaid or subsidized marketplace plans. The remainder of uninsured adults would not qualify for either: 11 percent earn below 100 percent of poverty and live in a state that did not expand Medicaid;5 8 percent have incomes at or above 400 percent of poverty and are ineligible for the tax credits; and 25 percent were foreign-born Latinos and may be ineligible for Medicaid or subsidized plans because of their immigration status.
