In January 2013, the Urban Institute launched the Health Reform Monitoring Survey (HRMS), a survey of the nonelderly population, to explore the value of cutting-edge, Internet-based survey methods to monitor the Affordable Care Act (ACA) before data from federal government surveys are available. Topics covered by the 12th round of the survey (third quarter 2016) include self-reported health status, type of health insurance coverage, access to and use of health care, out-of-pocket health care costs, health care affordability, health insurance literacy, feelings of unfair treatment by doctors and other health care providers, experience with health insurance marketplaces, awareness of ACA provisions, and rating of neighborhood characteristics. Demographic information collected by the survey includes age, gender, sexual orientation, marital status, education, race, Hispanic origin, United States citizenship, housing type, home ownership, internet access, income, employment status, employer size, body mass index, and whether the respondent reported an ambulatory care sensitive condition or a mental or behavioral condition.
