NOTE: Deaf-blindness, traumatic brain injury, and visual impairments are not shown because they each account for less than 1 percent of children served under IDEA. Due to categories not shown, detail does not sum to total. Includes children and youth in the 50 states, the District of Columbia, and the Bureau of Indian Education schools.
