Term assisted living implies to live with assistance of others. It gained popularity during the decade of 90's when younger generation could not cope with the care of older or senior citizens after being sandwiched between cares for children and parents coupled with preoccupations of jobs, business and other daily routines.

The concept of senior assisted living evolved from making arrangements for senior citizens who cannot take care of themselves in the midst of pangs of solitude, chagrin of the problems of old age and requirements of communities. It incorporates complete residential facilities, privacy, assistance of others and supervision of daily activities of life, health care, safety and wellbeing. Mostly assisted living is provided in senior communities.

Though senior generation dependent on assisted living do not need constant 24 hour consonant medical care like that provided in nursing homes, they still need assistance in carrying out daily activities of life. The philosophy of assisted living is to promote independence and dignity of the older generation in providing their services. Though no federal law in the United States exists for assisted living, however, every state uses licensure terms "assisted living" as along with a host of other terms like residential care home, assisted care facilities and senior assisted living.
