Definition: Estimated percentage of children ages 1-17 who have ever been told by a doctor that they have asthma (e.g., in 2019-2020, 12.4% of California children had been diagnosed with asthma in their lifetimes).
Data Source: UCLA Center for Health Policy Research, California Health Interview Survey (Feb. 2022).
Footnote: These estimates are based on a survey of the population and are subject to both sampling and nonsampling error. The notation S refers to data that have been suppressed because the sample size was lower than 50 (for ages 0-17), the value was less than 0.1%, or the estimate was suppressed by the UCLA Center for Health Policy Research. Data may have wide margins of error and should be treated with caution. For more information and margins of error around specific estimates, visit the California Health Interview Survey. N/A means that data are not available.
