WASHINGTON – Data released by the Obama administration on Wednesday showed California continues to lead the nation in health care signups under the Affordable Care Act.

Just over 728,000 people selected insurance plans on the Covered California web site from Oct. 1 to Feb. 1, according to the Department of Health and Human Services.

No other state had that many enrollments. Florida was second in the nation with nearly 297,000 and New York was third with nearly 211,300 people signing up.

Across the U.S., 3.3 million people have signed up on insurance "exchanges" set up by 14 states and the District of Columbia and the federal government, the data showed.

"(It's) very encouraging news," HHS Secretary Kathleen Sebelius said. "We're seeing a healthy growth in enrollment … 53 percent more Americans are signed up today than were signed up at the end of December."

A quarter of California's enrollees were between the ages of 18 and 34, a key demographic. The law's supporters say the more young people sign up the more coverage costs will come down. California's total was in line with the national trend.
