To gauge the perspectives of Americans on the marketplaces, Medicaid, and other health insurance issues, the Commonwealth Fund Affordable Care Act Tracking Survey interviewed a random, nationally representative sample of 2,410 adults ages 19 to 64 between November 2 and December 27, 2017, including 541 people who have marketplace or Medicaid coverage. The findings are compared to prior ACA tracking surveys, the most recent of which was fielded between March and June 2017. The survey research firm SSRS conducted the survey, which has an overall margin of error is +/– 2.7 percentage points at the 95 percent confidence level.
