Target-Setting Method: 
Minimal statistical significance
Target-Setting Method Justification: 
The target is the smallest improvement that results in a statistically significant difference when tested against the baseline value, assuming the same standard error for the target as the baseline.

Number of children aged 5 to 17 who missed school days among those who report an episode of asthma or an asthma attack in the past year


Number of children aged 5 to 17 years who report having an asthma attack in the past year

Changes Between HP2010 and HP2020: 
This objective differs from Healthy People 2010 objective 24-05 in that objective 24-05 was divided into separate objectives for children (RD-5.1) and adults (RD-5.2). The definition was modified from the average number of school or work days lost due to asthma to the percentage of persons who miss school days (RD-5.1) or work days (RD-5.2) due to asthma.
