Traditionally, young adults were more likely to be uninsured than any other age group.

Some are making the switch from school to work. Others are holding down low-wage jobs that don’t usually come with health care. And some _ termed the “invincibles” _ pass up job-based health insurance because they don’t think they’ll use it and would rather get extra money in their paychecks.

Other early coverage expansions in the health care law have not worked as well, including a special program for people with health problems who got turned away by private insurers. Many applicants found the premiums unaffordable.

Young adults are a less expensive group to cover than people who are middle-aged, and many companies have spread the extra premiums among their workers. Benefits consultant Delloite LLP has projected additional health plan costs in the range of 1 percent to 2 percent for covering young adults.
