社会的孤立
Social isolation impacts approximately 24% of older adults in the United States, approximately 9 million people. The elderly have a unique set of isolating dynamics that often perpetuate one another and can drive the individual into deeper isolation. Increasing frailty, possible declines in overall health, absent or uninvolved relatives or children, economic struggles can all add to the feeling of isolation. Among the elderly, childlessness can be a cause for social isolation. Whether their child is deceased or they didn't have children at all, the loneliness that comes from not having a child can cause social isolation. Retirement, the abrupt end of daily work relationships, the death of close friends or spouses can also contribute to social isolation. In the United States, Canada, and United Kingdom, a significant sector of the elderly who are in their 80s and 90s are brought to nursing homes if they show severe signs of social isolation. Other societies such as many in Southern Europe, Eastern Europe, East Asia, and also the Caribbean and South America, do not normally share the tendency towards admission to nursing homes, preferring instead to have children and extended-family of elderly parents take care of those elderly parents until their deaths. On the other hand, a report from Statistics Norway in 2016 stated that more than 30 percent of seniors over the age of 66 have two or fewer people to rely on should personal problems arise. Even still, nearly half of all members of senior communities are at high risk for social isolation, this is especially prevalent with seniors of a lower education and within the lower economic class and compounded with diminished availability of socializing options to these lower class individuals.  There has also been an observed increase in physical gait among members of these communities.
