The Department of Health and Human Services announced today that 4.2 million people have signed up for private health insurance through the online insurance marketplaces established by the Affordable Care Act.

The new numbers reflect a jump in enrollment of one million people in the past month. About 25 percent of people signing up for coverage through February were between the ages of 18 and 34. The report indicates that 63 percent of people chose silver plans, while 18 percent chose the less expensive bronze plans. Eleven percent chose gold, six percent chose platinum and one percent chose basic catastrophic plans. In addition, more women than men have signed up for the plan–55 percent, as compared to 45 percent of men.
