The "Annual Disability Statistics Compendium" is a publication of statistics about people with disabilities and about the government programs which serve them. It is modeled after the "Statistical Abstracts of the United States," published yearly by the U.S. Department of Commerce. The "Compendium" is designed to serve as a summary of government statistics. The 2015 "Annual Disability Statistics Compendium" underwent significant revisions this year. Over 100 tables have been added or expanded with additional age ranges--the "Compendium" now has tables representing the aging population whenever possible. The Health Insurance and Medicaid and Medicare sections from previous years were combined, and time trend data was added where available. The introductory text of each section has been revised. This text now describes table sources and content, defining disability and employment for any given section. The text acknowledges the source information at the bottom of each table, where the source of data appearing in each table is presented. These sources contain additional statistical information about the ways the data were collected and the statistics were generated. The glossary has been expanded to assist in the interpretation of the statistics contained in the "Compendium." Words and phrases defined in the glossary are now in boldface text throughout the report. [For "2015 Disability Statistics Annual Report.
