title: Chronic Conditions Causing Activity limitation United States - July 1963-June 1965.
abstract: This is the third report from the Health Interview Survey dealing with the causes of activity limitation. Previous reports on this subject are "Chronic Conditions and Activity Limitation, United States, July 1961-June 1963" (Vital and Health Statistics, Series 10, No. 17) and "Chronic Conditions Causing Limiation of Activities, United States, July 1959-June 1961" (Health Statistics, Series B, No. 36). Some of the statistics in the earlier reports have been updated in the present publication. For example, the distribution of selected causes of limitation among chronically limited persons according to the degree of severity of limitation is shown in each of these reports, and the chronological sequence of these distributions forms a source of data for valid trend comparisons. Comparability has been ensured by the absence of major alterations of questionnaire items related to this subject and by the use of the same chronic condition list for each report.
