Notes:  See Part B child count data notes for an explanation of individual state differences.
 
Percent = Number of students ages 6 through 21 served under IDEA, Part B, divided by the number of students
age 6 through 21 in the population multiplied by 100.  See Table 1-3 for the numerator and Tables C-4 and C-5 for the denominator.
 
The sum of the percentages for individual disabilities may not equal the percentage of all disabilities because of rounding.
