WASHINGTON (AP) -- Two new surveys find a big drop in the number of young adults without health insurance since last year -- and President Barack Obama's overhaul is getting credit instead of criticism.

A government health statistics survey released Wednesday finds nearly 1 million more adults ages 19-25 gained insurance in the first three months of this year. Separately, a Gallup survey also out Wednesday reports that the share of adults 18-25 without coverage dropped from 28 percent last fall to 24.2 percent by this summer.

The health care law allows adult children to stay on their parents' plan until they turn 26. Coverage for young adults is increasing at a time when a weak economy is leaving more workers uninsured. Health and Human Services Secretary Kathleen Sebelius says that shows the law is working.
