Percent of Children with Asthma


Percent of people younger than 18 who currently have asthma.

Source:, America’s Children: Key National Indicators of Well-Being. The estimates are based on data from the National Center for Health Statistics, National Health Interview Survey.

Methodological Notes: 

In the National Health Interview Survey, the child’s parent is asked, “Has a doctor or other health professional ever told you that your child has asthma?” If the parent answers yes to this question, then they are asked, “Does your child still have asthma?”  Children are identified as currently having asthma if they have ever been diagnosed with asthma and still have it.
