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.

The 2015 CHAS was a telephone survey – both cell phones and landlines – of 10,136 randomly-selected households in Colorado. It was administered between March 2 and June 26 by Social Science Research Solutions (SSRS), an independent research company. Survey data were weighted to accurately reflect the demographics and distribution of the state’s population.

New questions were added to the 2015 survey to help assess the Affordable Care Act (ACA) in Colorado, including the launch of Connect for Health Colorado, the online insurance marketplace. 

In-depth CHAS data, including data for all 21 Health Statistics Regions for all four survey years, is available here.
