Uninsured in U.S. Remain Steady as Health Exchanges Await

There was little shift in the share of people in the U.S without health insurance in the first quarter of 2013, a trend likely to change when new coverage marketplaces open next month as part of the health overhaul law.

Forty-six million people didn’t have health insurance in the first quarter of the year and 57 million people, or 19 percent of the U.S., were without coverage at some point in the prior 12 months, according to a survey by the Centers for Disease Control and Prevention.
