BATON ROUGE, La. (AP) — Enrollment in health insurance plans through the federal marketplace has swelled, with more than 17,500 people in Louisiana signed up for coverage by December.

Federal health officials released updated enrollment figures Monday, along with details of who is getting the government-subsidized private insurance created under President Barack Obama's health revamp.

In Louisiana, more women have signed up than men, and one-third of those getting insurance are in the older, costlier age ranges of 55 to 64 years old.

Four out of every five Louisiana residents who registered for insurance through the marketplace have received federal financial subsidies to help cover costs.

Enrollment opened Oct. 1 and continues until March 31. More than 2 million Americans had enrolled through the end of December. In Louisiana, the number reached 17,548.
