The administration is reporting that 462,125 people selected health insurance plans on the federal exchange, Healthcare.gov, in the first week of open enrollment. Nearly half—48 percent—were new customers, buying plans for the first time. That's good news, indicating that outreach to the uninsured is working and there could be another significant reduction in the uninsured rate after this round. The new numbers, released by Health and Human Services Wednesday, show a faster start to open enrollment this year than in 2013.
