A few key stats of a new study put out by the RAND Corporation on Obamacare’s exchange enrollment:

  • Of the 40.7 million who were uninsured in 2013, 14.5 million gained coverage, but 5.2 million of the insured lost coverage, for a net gain in coverage of approximately 9.3 million. This represents a drop in the share of the population that is uninsured from 20.5 percent to 15.8 percent.
  • The 9.3 million person increase in insurance is driven not only by enrollment in marketplace plans, but also by gains in employer-sponsored insurance (ESI) and Medicaid.
  • Our estimates suggest that only about one-third of new marketplace enrollees were previously uninsured. While this percentage seems low in absolute terms, it is slightly higher than an earlier figure reported by McKinsey & Company.[1]
