New AsthmaStats
Prevalence of Asthma Attacks among those with Current Asthma by State, Children -- 2014-2017 NHIS
Asthma Attacks among People with Current Asthma, 2014–2017

Nearly half the people with current asthma had one or more asthma attacks in the past 12 months

In an asthma attack, the airways become inflamed, making breathing difficult. On average, 50.2% of children and 44.7% of adults with current asthma had one or more asthma attacks during 2014–2017. The percentage of asthma attacks varied by state. Among children, the median percentage was 51.0%, but it ranged from 23.1% in Nebraska to 81.7% in Wyoming. Among adults, the median percentage was 44.8%, but it ranged from 32.7% in North Dakota to 66.6% in Alaska.
