The 2011 Colorado Health Access Survey coincided with a deep economic recession. It documented a large increase in the number of Coloradans without health insurance coverage — from 678,000 in the 2008-2009 survey to 829,000 in 2011. This increase from 14 percent to 16 percent of the population meant one in six Coloradans lacked health insurance.
What is the CHAS?
The Colorado Health Access Survey – the CHAS – is the premier source of information on health insurance coverage, access to health care and use of health care services in Colorado. More than 10,000 households in the state have been interviewed every other year since 2009, allowing comparisons across a time marked by sweeping changes in health policy.
