An assisted living residence or assisted living facility (ALF) is a housing facility for people with disabilities or for adults who cannot or who choose not to live independently. The term is popular in the United States. Still, the setting is similar to a retirement home, in the sense that facilities provide a group living environment and typically cater to an older adult population. There is also Caribbean assisted living, which offers a similar service in a resort-like environment.

Health care, or healthcare, is the improvement of health via the prevention, diagnosis, treatment, amelioration or cure of disease, illness, injury, and other physical and mental impairments in people. Health care is delivered by health professionals and allied health fields. Medicine, dentistry, pharmacy, midwifery, nursing, optometry, audiology, psychology, occupational therapy, physical therapy, athletic training, and other health professions all constitute health care. The term includes work done in providing primary care, secondary care, and tertiary care, as well as in public health.
