In the Chartbook, we report analyses from more than one survey, since surveys use different definitions of disability. All charts are prepared from published tables and documents. Each term which is uniquely defined by the surveys is bold-faced on the page and is defined in the Glossary. Each page notes the survey and source of analysis. A Bibliography provides references for the sources consulted.
Detailed information covering technical issues of each survey is provided in the Appendix.
Section 1 provides estimates of people with disabilities in the United States. Causes of disabilities, and medical costs, are covered in Section 3. Section 4 examines aspects of two particularly important disability populations, the elderly and children. Finally, work disability is reviewed in Section 5. Demographic data and statistical information on disability contribute to the understanding of the scope of disability issues in the United States, developing disability policy, and planning, conducting, and evaluating services for individuals with disabilities.
