Since Americans began enrolling in health care programs under the Affordable Care Act, the percentage of uninsured people in California has dropped by half, according to a new survey.
The survey was conducted from April to June and found that 11 percent of Californians were uninsured.
From July 2013 to September 2013, before the first open healthcare enrollment period began, 22 percent of Californians were uninsured.
This is significantly higher than the national drop in the uninsured rate, which went from 20 percent to 15 percent.

California was the first state to develop its own health care marketplace when the Affordable Care Act was rolled out last year, and it has also expanded Medicaid eligibility. The survey found California has pursued an "aggressive" campaign to enroll people, with awareness of the marketplace going up from 42 percent to 75 percent in the state.
Nationally, about 9.5 million adults have become insured since the first open enrollment period, which began in October 2013 and lasted through March. More than half of the newly insured are between the ages of 19 and 34.
The survey was published Thursday by the Commonwealth Fund, a private foundation that conducts research on health care issues.
The next open enrollment period for health insurance begins Nov. 15.
