title: Limitation of activity due to chronic conditions United States, 1969 and 1970.
abstract: During 1969 and 1970 an estimated average of 23,237,000 persons, about 11.7 percent of the civilian, noninstitutionalized population of the United States, were reported in health interviews to be limited to some extent as a result of chronic disease or impairment. Limitation of activity is a measure of long-term disability resulting from chronic conditions. It is defined as inability to carry on the major activity for one's age-sex group, such as working, keeping house, or going to school; restriction in the amount or kind of major activity; or restriction in relation to other activities, such as recreational, church, or civic interests.
