Under the healthcare overhaul, young adults who buy their own insurance will carry a heavier burden of the medical costs of older Americans, a shift expected to raise insurance premiums for young people when the plan takes full effect. Beginning in 2014, most Americans will be required to buy insurance or pay a tax penalty. That's when premiums for young adults seeking coverage on the individual market would likely climb by 17% on average, or roughly $42 a month, according to an analysis of the plan conducted for The Associated Press.
