Methodology Notes

Persons are classified as having missed school if they responded “1-365” to the question about number of days missed.

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.
