A couple of weeks ago there was much ado about a new Commonwealth Fund survey which found that nationally, the uninsured rate had been cut by 25% (from 20% down to 15%). Well, buried in that study was this bit about California specifically:

The percentage of uninsured Californians has been cut in half since the federal health law began expanding coverage nine months ago, according to a new national survey.

In September of 2013, 22 percent of California adults were uninsured. By last month, that number had fallen to just 11 percent, the biggest drop among the nation’s six largest states.
