INDIANAPOLIS (AP): More than 40 percent of Indiana residents who could have chosen a health plan on the new insurance markets in the first year of the historic health care overhaul didn't sign up.

Data released Thursday by the U.S. Department of Health and Human Services show that a total of nearly 230,000 Indiana residents were eligible to enroll in a marketplace plan, but only about 132,000 had done so by the March 31 deadline.

Nearly 30 percent of those signing up in Indiana were age 55-64. About one-fourth were age 18-34.

Fifty-six percent of the Indiana residents who enrolled were women, and 44 percent were male.

Nationally, the Obama administration says 8 million Americans chose a health plan.

Indiana chose not to set up a state health insurance exchange.
