Last week the administration released data on the number of people who have applied for, and been enrolled in, insurance through the Affordable Care Act (ACA).  As has been widely reported, 106,185 people enrolled in the state and federal Marketplaces, and 396,291 enrolled in Medicaid plans, for a total of 502,446 enrolled.

How well are these state-based and federal Marketplaces doing in enrolling people, especially relative to the number of uninsured in the states?  Some overall impressions, presented in the attached table:

  • The state based Marketplaces have been way more successful in enrolling people -- while 56.6% of those who applied through state Marketplaces have obtained coverage (either a Marketplace plan or Medicaid), only 21.2% of those applying through federal-based Marketplaces have obtained coverage.
  • Overall, 1.1% of the uninsured were enrolled during October, but the percentage covered is much higher (2.1%) in state based Marketplaces than in states enrolled in the federal Marketplace (0.6%)
  • a higher proportion (2.1%) of the previously uninsured have been enrolled in Medicaid as a proportion of that eligible population (defined as people living in families with incomes of 138% of the federal poverty line or lower), as compared to the proportion (0.4%) of those not eligible for Medicaid (139% of the FPL or higher).
  • Some states have enrolled a much higher proportion of the previously uninsured than others: Kentucky (5.3%), Vermont (5.7%) and Washington (5.8%), while 24 of the 36 states relying on the federal Marketplace have enrolled less than 1% of the uninsured.  The state by state breakdown is presented here.
  • Two states (Vermont and Washington) enrolled more than 10% of the Medicaid-eligible population.
  • Even though not all states in the U.S. have expanded Medicaid, every state in the country has seen an increase in Medicaid enrollment (since in those states not expanding Medicaid, some individuals were already eligible, but not yet covered).
