Version V1

This data collection was designed to obtain information about the services and resources of the various types of long-term care facilities in the United States, i.e., chronic care institutions (providing care for people with chronic conditions, diseases, and handicaps), institutions that provide care for the mentally ill and mentally handicapped, nursing homes, homes for the aged, and residential schools and treatments centers. Six major areas of concern were examined in this study: (1) the appropriateness of placement/admission and discharge, plus possible alternatives, (2) the quality of life within the institutional environment, (3) the residents' rights and legal status, (4) the medical and non-medical services provided and needed, (5) the sources of financing such care, and (6) the impact of government programs and policies upon the costs and provision of certain types of service. This information was collected from 9,090 residents of 851 institutions and from 3,289 of their family members. Administrative staff at each resident's facility also provided information about that facility as well as the sampled resident. Data about the resident's institution include its basic characteristics, e.g., type of care provided, ownership, number of beds, occupancy rate, and services and programs offered. Resident data include basic social and demographic characteristics, reason for institutionalization, cost of care, current activities, type of treatment, and the physical limitations of the institutional population. Family data examine the next of kin's relationship to the resident, e.g., relative's proximity to the institution, frequency of visits, and monetary contributions to the resident, as well as the next of kin's demographic characteristics and views of the resident and his or her institutionalization.

The National Survey of Institutionalized Persons data (SIP) are organized in a single data file comprised of three types of records: Institution, Resident, and Family. Each Family record obtained was merged onto the appropriate Resident data, which was in turn merged onto the appropriate Institution data. Resident (V375-V700) and Family (V701-V864) records follow immediately after the Institution (V1-V374) records in which they were identified. For policy or patient health reasons, 44 institutions did not permit interviewing of residents, and 5,801 residents had no corresponding family interviews.

National multistage stratified probability sampling was used for this survey. It was a three-stage design encompassing, respectively, a sample of institutions, a sample of residents within the selected institutions, and a subsample of the families of the selected residents. Each stage of selection constituted a national probability sample. A design objective of the survey was to provide statistical information of roughly comparable reliability for each of 18 strata of institutions, i.e., six types of facilities by three size categories. In effect, therefore, 18 independent samples were selected and interviewed. The basic frame from which the institution sample was taken was the 1973 Master Facility Inventory. In general, within each of the 18 strata, institutions were chosen systematically with probability proportionate to their sizes, i.e., the number of beds. Some strata contained relatively few institutions, in which case all the institutions were included in the sample with certainty. Penal and juvenile detention facilities were excluded from the sampling because they serve as incarceration institutions rather than personal care institutions.

Residents of long-term care institutions in the United States, excluding penal and juvenile detention facilities, who were 14 years of age or older, and mentally and physically able to respond.

1984-05-03 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Checked for undocumented or out-of-range codes.


  • Data in this collection are available only to users at ICPSR member institutions.
