Colorado Health Access Survey

Colorado’s Best Source of Insight and Information About Health, Coverage, and Care

The Colorado Health Access Survey – the CHAS – is the premier source of information on health coverage, access to health care, and the factors that influence health in Colorado. 

More than 10,000 households in the state have participated every other year since 2009, allowing comparisons across a time marked by sweeping changes in health policy. Recent surveys have expanded to cover factors closely tied to health, including housing, food access, and experiences of discrimination. The survey provides a credible source of information about key trends and challenges facing Coloradans that is not available through any other source.

2021 CHAS

The COVID-19 pandemic brought more than a novel and dangerous virus to Colorado. The 2021 Colorado Health Access Survey (CHAS) documents historic shifts in health, access to care, and social and economic conditions. More people than ever before reported challenges with their mental health, especially young adults.

Colorado’s Essential Health Survey

The CHAS plays a central role in efforts to improve health for everyone in Colorado. 

In the past decade, the survey has measured the effects of the Affordable Care Act and identified work left to do to improve access to health care. More recently, it has examined social factors such as housing, food access, and discrimination in health care. The 2021 survey looks at the effects of the COVID-19 pandemic. 

The survey’s large sample size allows for statistically significant samples in urban and rural areas and by age, race, and income. 

Policymakers, state agencies and local governments use the CHAS to measure access to care in Medicaid and to identify needs in behavioral health. Health systems and providers use it to help understand access to care in the areas they serve. Community-based organizations rely on CHAS data to evaluate local needs and inform their strategic plans and programs. Researchers and journalists use it to track the impact of policy shifts and gain insight into the state’s evolving health needs.
