About the Survey

Approximately 50,000 Missouri adults were randomly called to participate in the 2022 Missouri County-level Study (CLS). The 2022 CLS expanded upon data from previous studies conducted in 2007, 2011 and 2016. 

The Missouri Department of Health and Senior Services collaborated with the University of Missouri-Columbia (MU) Health and Behavioral Risk Research Center to conduct the CLS. Trained interviewers from MU called landline and cell phone numbers throughout 2022. Weekday calls occurred between 9 a.m. and 9 p.m., while weekend calls began later and ended earlier. 

The 2022 CLS produced prevalence estimates for all 114 Missouri counties and the City of St. Louis. A minimum of 300 interviews were conducted in most counties. A greater number of interviews were conducted in select counties (e.g., Boone, Buchanan, Clay, Cole, Greene, Jackson, Jasper, St. Charles, St. Louis and the City of St. Louis) so that comparisons of health status and health-related behaviors by race/ethnicity and rural/urban residence could be made.
