HCR Update from Mark Sanna: Data released yesterday by the Centers for Disease Control and Prevention show that in the first quarter of 2011, the percentage of adults between ages 19 and 25 without health insurance fell 3.5 percentage points — to 30.4%. That translates to about an additional 1 million people that got coverage from the previous year. It's the third survey in recent weeks to credit a piece of the health law with giving more young adults insurance.
