The "Annual Disability Statistics Supplement" is a companion report to the "Annual Disability Statistics Compendium" (ED595182). The "Supplement" presents statistics on the same topics as the "Compendium" with additional categorizations by demographic characteristics including age, gender and race/ethnicity. In addition to the "Supplement," a companion "Annual Report" (ED595177) is available, providing graphic representations of key findings. [For the 2017 Supplement, see ED583259.]
