Data from the Survey of Income and Program Participation (SIPP) conducted during 1984 and 1985 by the Bureau of the Census are displayed in tables and charts. Data are derived from disability questions which were divided into four groups. The first group asked about the ability of persons 15 years and older to perform such sensory and physical activities as seeing, hearing, walking, and speaking. The second group of questions were asked of persons 16 to 72 years old and focused on the ability to work at a job. The third group of questions asked persons 15 years and older whether the help of another person was required for such activities as doing light housework, preparing meals, taking care of personal hygiene, and getting around. The fourth group of questions concerned children under 18 years of age and asked if the child had a long-lasting physical condition that limited his/her ability to walk, run, or play or a long-lasting mental or emotional problem that limited his/her ability to learn or do regular schoolwork. Some of the charts present data in terms of race, age and sex. Appendices provide a SIPP overview, survey definitions and explanations, sources and reliability of estimates, and a facsimile of the 1984 SIPP Third Wave Questions on disability status. (CB)
