The countries of the world, both developing and developed, are aging. Some already have sizeable populations of elderly persons and others are beginning to experience an aging of their populations for the first time. The causes of population aging in countries of the world are many and include improved medical technology, use of birth control, and emigration of younger members of a society. The demographic "explosion" of the elderly comes at a time of rapid Westernization with changes in the tradition of family caregiving responsibility for elderly members of the family. Simultaneously, even in advanced societies, economic recessions and competing demands jeopardize continuing public responsibility for the elderly.
