Current asthma rates are not the same across demographic groups. This page describes current asthma rates, defined as those who have ever been diagnosed with asthma by a healthcare professional and report still having asthma, by the following demographics: sex and age, race/ethnicity, Hispanic subgroups, family income, health insurance coverage, and state.

 

 

Current Asthma Rates by Sex and Age

  • Among children, current asthma is more common for males (8.3%) than females (6.7%). However, among adults, females (9.8%) are more likely than males (5.5%) to still have asthma.
 

Current Asthma Rates by Race/Ethnicity

  • Blacks and American Indian/Alaska Natives have the highest current asthma rates compared to other races and ethnicities. In 2018, Blacks (10.9%) were 42 percent more likely than Whites (7.7%) to still have asthma.
  • Hispanics (6.4%) and Asians (4.0%) had lower current asthma prevalence rates than other racial and ethnic groups.
 

Current Asthma Rates by Hispanic Subgroups

  • While asthma rates are relatively low for Hispanics overall, rates vary significantly among subgroups. Puerto Ricans in the continental United States have the highest current asthma rate of any racial or ethnic group, at 14.0 percent over 2016 to 2018.
 

Current Asthma Rates by Family Income

  • In 2018, current asthma rates were significantly higher (11.0%) among those with a family income below the poverty threshold as compared to above the poverty threshold.
 

Current Asthma Rates by Health Insurance Coverage

  • In 2018, current asthma rates among adults ages 18 to 65 were highest for those on Medicaid and lowest for those with no medical insurance.
 

Current Adult Asthma by State

  • In 2018, current asthma rates among adults ranged from 7.4 percent in Texas to 12.3 percent in Maine and West Virginia.

    • * National child asthma prevalence is based on data from 31 states and Washington, D.C.
    • Child asthma data is from 2018 unless an earlier year is noted, in which case that is the most recent year of data available. If a state has not collected child asthma data since 2011, no rate is listed.
