PHILADELPHIA (CBS) — Federal officials say nearly a million people signed up for health insurance under the Affordable Care Act in February, including some 36,000 Pennsylvanians.

February enrollment brings the number of previously uninsured Pennsylvanians, now enrolled in plans through, to nearly 160,000. That’s just 13 percent of the total number eligible but Bill England of the non-profit Enroll America was upbeat.

“We’re certainly making progress in reducing the number of uninsured in the Commonwealth and we’re feeling good about that,” England said.

Of those, just 27 percent are under age 35, far short of the 40 percent that insurers estimate is necessary to keep premiums affordable.
