Gallup might use a broader definition of "young adult" than the Commonwealth Fund but came to the same conclusion: They don't know much about the Patient Protection and Affordable Care Act.
When Gallup surveyed 1,021 U.S. adults ages 18 and older in mid-August, it found only 15 percent of all participants "were very familiar" with PPACA. Eighteen percent said they were "not too familiar," and 12 percent admitted they were "not all familiar" with the law.
Just 10 percent of the participants ages 18 to 34 said they were very familiar with the law, 53 percent said they were somewhat familiar with it, and 36 percent said they were not too familiar with it or not at all familiar with it.
Andrew Dugan, a Gallup analyst, wrote that the new survey raise questions about how likely it is healthy young consumers will flock to the exchanges.
