MONDAY, Jan. 13, 2014 (HealthDay News) -- Nearly 2.2 million Americans had selected health plans through the federal and state marketplaces as of late December, and nearly one in four was a young adult, the Obama administration disclosed Monday.
"The numbers show that there is a very strong national demand for affordable health care made possible by the Affordable Care Act," Health and Human Services (HHS) Secretary Kathleen Sebelius said during a news conference Monday afternoon.
Twenty-four percent of people who chose a plan were in the key 18-to-34-year-old demographic.
Attracting enough young adults to the mix should keep health insurance rates more affordable, experts say. Young people tend to be healthier, helping to offset the risk of covering older, sicker adults.
"For the 18-34 age band, we would want at least 32 percent of the adult sign-ups [people ages 18 to 64] to be in that category," said David Axene, president and consulting actuary at Axene Health Partners, of Murrieta, Calif.
"Materially less than that leads to subsidy concerns," he added.
Sebelius highlighted a rosier statistic during Monday's news conference, noting that 30 percent of enrollees were under age 35. But that figure includes people 17 and younger who are not yet considered adults.
"It's hardest to enroll the younger people, and so they're not going to enroll until the deadlines get closer," said Gary Claxton, vice president and director of the Health Care Marketplace Project at the Henry J. Kaiser Family Foundation in Washington, D.C.
Open enrollment in the health marketplaces ends March 31.
"What matters obviously is what happens by the end of March," Claxton said.
Mike Hash, director of the HHS Office of Health Reform, told reporters Monday that "the trends so far are suggestive of an appropriate mix in the marketplace."
With 11 weeks to go before the enrollment period ends for insurance coverage in 2014, "we expect an increase in the proportion of young adults as we go forward," he said.
