These data describe tenants of subsidized elderly housing who used services provided by the Robert Wood Johnson Foundation Supportive Services Program in Senior Housing (RWJF SSPSH), and document use of these services. Services provided by the RWJF SSPSH program included housekeeping, transportation, meals, running errands, assistance with forms, personal care, and home health care. Three types of data comprise this collection: (1) participant information taken at first service delivery (Part 1), (2) administrative logs describing services delivered to each client (Parts 2-7), and (3) information on each site participating in the program (Part 8). Information about the participants includes age, gender, living arrangements, monthly income, health status, ability to do light and heavy tasks, and ability to do personal tasks. Information on service delivery includes the type and amount of each service delivered, whether the tenant paid for the service, how the service was funded, and the quarter in which the service was delivered. Site information includes subsidy type, building start date, type of location (urban, suburban, or rural), and whether the site had a full- or part-time service coordinator.
