Health Insurance Marketplace: Summary Enrollment Report For the Initial Annual Open Enrollment Period. Increase in Health Insurance Coverage


In addition to the more than 8 million people who have selected plans through the Marketplace during the initial open enrollment period (including SEP activity through 4-19-14), CBO recently estimated that an additional 5 million people have purchased coverage outside of the Marketplace in Affordable Care Act-compliant plans.13 Meanwhile, the Blue Cross Blue Shield Association estimates that its plans have enrolled 1.7 million in Affordable Care Act-compliant, off-Marketplace plans.14 Additionally, E-Health reports that 45 percent of its off-Marketplace enrollees from January through early March of 2014 were ages 18 to 34.15

Moreover, recent national surveys indicate that the number of Americans with health insurance coverage is growing, and the number of 18 to 64 year olds who are uninsured is declining. For example, Gallup has found a 3 percentage point decrease in the uninsured rate for adults (18 to 64) from the third quarter of 2014 to March 2014 (18 percent versus 15 percent, respectively, corresponding to a 7.26 million decline in the number of uninsured adults).16 Similarly, the Urban Institute estimates a 2.7 percentage point decrease in the uninsured rate for adults (18 to 64) from October 1, 2013 to March 31, 2014 (corresponding to a 5.4 million decline in the number of uninsured adults).17 Meanwhile, the RAND Corporation estimates a 4.7 percentage point decrease in the uninsured rate (corresponding to a net decrease of 9.3 million uninsured adults, ages of 18 to 64) from the last week of September 2013 through March 2014.18
