Definition and Source



Children ages 6 to 17 who missed 11 or more days of school per year due to illness or injury by age group.

Information on each child is based on responses of the parent or guardian in the household who was most knowledgeable about the sampled child. Survey did not have response options to indicate whether the child was home-schooled or did not go to school in the past 12 months. Additionally, response options were reported in continuous numbers in the 2011/12 NSCH, but were reported in five categorical ranges of missed school days starting in the 2016 NSCH.
