Older People Lead Sign-Ups for Insurance

People signing up for health insurance through the Affordable Care Act’s federal and state marketplaces tend to be older and potentially less healthy, officials said Monday, a demographic mix that could threaten the law’s economic underpinnings and cause premiums to rise in the future if the pattern persists.

Questions about the law’s financial viability are likely to become the next line of attack from its critics, as lawmakers gear up for the midterm elections this fall. Republicans quickly seized on the government’s progress report on Monday as evidence that the health insurance law would not work.

But administration officials expressed optimism that more young people would sign up in the months ahead, calling the latest enrollment numbers “solid, solid news” for the health care law.

Of those who signed up in the first three months, administration officials said, 55 percent are age 45 to 64. Only 24 percent of those choosing a health insurance plan are 18 to 34, a group that is usually healthier and needs fewer costly medical services. People 55 to 64 — the range just below the age at which people qualify for Medicare — represented the largest group, at 33 percent.
