This file provides data on 7,541 persons who were aged 70 and over at the time of the 1984 interviews. "The LSOA is designed to (a) provide mortality rates by demographic, social, economic, and health characteristics that are not available from the vital statistics system, (b) measure change in the functional status and living arrangements of older people, and (c) provide measures of health care use. It is also designed to describe the continuum from functionally independent living in the community through dependence, possibly institutionalization, and finally to death."
