Long term care is a variety of services that which help meet both the medical and non medical needs of the people with a chronic illness or disability who cannot care for themselves for a long period of time.
Long-term care may be needed by people of any age, although it is a more common need for senior citizens.
Using statistics of the US
Most but not all
persons in need of long-term care are elderly. Approximately 63% are
persons aged 65 and older (6.3 million); the remaining 37% are 64 years
of age and younger (3.7 million).
In short we can say that the elderly population of in the age group of above 65 years comprises most of the long term care.
