The aging process of the population, obviously in developed countries, involves many socio-economic and political changes. This demographic trend is due to the decreasing of birth rate and fertility rate on one hand, and, on the other hand, to the decrease of crude mortality and infant mortality rate. These mean that the rising proportion of the old people is greater cause of concern, because most of these people require considerable support, frequently in institutions, and often at public expense. Taking demographic data and trends as the starting point, the society has to focus on social protection and health policies in order to improve the quality of life for the elderly.
