*Aged 18+ years
**U.S. Total includes 49 states plus the District of Columbia and excludes the three territories. New Jersey was excluded because of not meeting the minimum data collection requirements.
CI denotes confidence interval.
§Sample size is the number of respondents answered current asthma question
If values for the standard error and the 95% confidence interval are not provided, the normal approximation to the binomial distribution does not apply due to small sample size.
When the Sample Size is less than 50, estimates are not precise and should be interpreted with caution.
