Asthma Among Adults and Children by Urban-Rural Classification Scheme, United States, 2016-2018.

Objectives: Although data on the prevalence of current asthma among adults and children are available at national, regional, and state levels, such data are limited at the substate level (eg, urban-rural classification and county). We examined the prevalence of current asthma in adults and children across 6 levels of urban-rural classification in each state.

Methods: We estimated current asthma prevalence among adults for urban-rural categories in the 50 states and the District of Columbia and among children for urban-rural categories in 27 states by analyzing 2016-2018 Behavioral Risk Factor Surveillance System survey data.
