The National Health Interview Survey showed an 8.3 percentage-point increase in young adults with insurance between September 2010 and June 2011, approximately 2.5 million adults.1 Census data and independent surveys showed similar increases,2- 4 but questions remain: What types of coverage did young adults acquire? Did trends differ for adults not affected by the dependent coverage provision or for particular racial/ethnic groups? Our study examines changes in insurance coverage for young adults from 2005 through 2010.
