1 Persons who answered "yes" to the questions "Have you EVER been told by a doctor or other health professional that you had asthma?" and "Do you still have asthma?".

2 Numbers within selected characteristics may not sum to total due to rounding and missing values.

3 The weighted number of survey participants of the intended population group with current asthma divided by the weighted number of all survey participants in the intended population group and then multiply by 100.

4 Persons who answered "male" or "female" to the question "Are you male or female?".

5 Poverty level is based on family income and family size using the U.S. Census Bureau's poverty thresholds. Poverty level was calculated separately using 10 imputed income files.

Notes:

For detailed estimates refer to 2020 Asthma-related Healthcare Use data web tables: https://www.cdc.gov/asthma/national-surveillance-data/healthcare-use.htm.

Note: in 2020 transitioned to using HCUP data to calculate asthma Emergency Department visits

1 Asthma as the primary diagnosis (ICD-10-CM Code: J45)

2 Crude rate per 10,000 U.S. Census 2020 population

3 Rate was calculated using the weighted number of visits for children aged 0–17 years divided by the U.S. Census 2020 resident population for children aged 0–17 years and multiplied by 10,000.

4 Rate was calculated using the weighted number of visits for adults aged 18+ years divided by the U.S. Census 2020 resident population for adults aged 18+ years and multiplied by 10,000.
