Definition: Estimated percentage of children ages 6-17 who missed and did not miss school in previous 12 months due to illness or injury, by special health care needs status and number of days missed (e.g., in 2024, 52.2% of California children with special health care needs missed 3 or fewer school days in the previous year due to illness or injury).
Data Source: U.S. Dept. of Health and Human Services, National Survey of Children's Health (Nov. 2025).
Footnote: Children with special health care needs (CSHCN) have or are at increased risk for a chronic physical, developmental, behavioral, or emotional condition and require health and related services of a type or amount beyond that required by children generally. These estimates are based on a survey of the population and are subject to both sampling and nonsampling error. The annotation [!] indicates that the margin of error for the estimate is greater than 5 percentage points but less than 10 percentage points.
