#Rounds to zero.

1 Totals are based on overall counts of children by type of disability; they are not based on summing the counts reported for the individual racial/ethnic groups or the counts reported by sex. (Due to data limitations, summing the counts by disability type within each racial/ethnic group would result in a total overcount of 77 children. Because of missing data on type of disability by sex, summing the counts by disability type for males and females would result in undercounts.)

2 For 3- to 5-year-olds, no data are available on type of disability by sex. For 6- to 21-year-olds, data include only those children served for whom both sex and type of disability were reported. About 1 percent of all 6- to 21-year-olds served are excluded from this table because of missing data. Due to changes in reporting requirements in the 2019-20 data collection, the number of 6- to 21-year-olds served includes some 5-year-olds enrolled in kindergarten.

3 Other health impairments include having limited strength, vitality, or alertness due to chronic or acute health problems such as a heart condition, tuberculosis, rheumatic fever, nephritis, asthma, sickle cell anemia, hemophilia, epilepsy, lead poisoning, leukemia, or diabetes.

4 Percentages for 3- to 5-year-olds by sex are based on projected total public school enrollment in prekindergarten and kindergarten by sex. Percentages for 6- to 21-year-olds by sex are based on projected total public school enrollment in grades 1 through 12 by sex. Data on total public school enrollment by grade are available in table 203.10, but data on total enrollment by sex are unpublished. Percentages for 3- to 21-year-olds by race/ethnicity are based on projected total public school enrollment in prekindergarten through grade 12 by race/ethnicity. For total public school enrollment by race/ethnicity, see table 203.50.

NOTE: This table includes 2015-16 data for 3- to 21-year-olds in Wisconsin due to unavailability of more recent data for children served in Wisconsin. Data by disability type for Iowa are imputed based on the reported 2018-19 percentage distribution by disability type applied to the 2019-20 total number of children served in Iowa. Although data are for the 50 states and the District of Columbia, data limitations result in inclusion of a small (but unknown) number of students from other jurisdictions. Race categories exclude persons of Hispanic ethnicity. Detail may not sum to totals because of rounding.
