The term “home and community-based long-term services and supports” (HCBS) refers to assistance with daily activities that generally helps people with disabilities to remain in their homes. Many people with functional limitations or cognitive impairments need assistance with activities of daily living (ADLs) such as bathing, dressing, and using the toilet, or instrumental activities of daily living (IADLs) such as shopping and doing laundry. Services such as personal care, chore assistance, transportation, congregate meals, or adult day services all constitute HCBS. People of all ages with disabilities who use these services live in a variety of settings: their own homes or apartments, assisted living facilities, adult foster homes, congregate care facilities, or other supportive housing. Estimates of the population with some type of limitation on daily activities vary, depending on the definition of “disability.” In 2002, about 8.7 million people age 65 or older living in the home had a limitation in at least one ADL or IADL (almost 27 percent of the population). About 6 percent of this age group (2 million people) had more severe disabilities (limitation in 3 or more ADLs).
