Current Asthma Demographics

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 (9.5%) than females (7.3%). However, among adults, females (9.8%) are more likely than males (5.4%) 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 2017, Blacks (10.1%) were 25 percent more likely than Whites (8.1%) to still have asthma.
  • Hispanics (6.4%) and Asians (4.4%) had lower current asthma prevalence rates than other racial and ethnic groups.

Current Asthma Rates by Hispanic Subgroups
