"The vast majority of Americans, 81%, say they are aware of the 2010 Affordable Care Act's (ACA's) requirement that most Americans must carry health insurance or pay a fine. Americans who are currently uninsured -- those most directly affected by this requirement -- are much less likely to be aware of the provision, with 56% saying they know about it and 43% saying they are unaware."
