Abstract :
Today, all nations are moving towards the ageing of their populations. The objectives of the present article are (1) to describe the distribution of the world older population, (2) to discuss the home of the world older population in the future, and (3) to explain why developed countries have a higher proportion of older in their population structure. The materials in this paper were taken from a research using a content analysis design. The results of the study show the world older population is not evenly distributed. From 607.1 million older populations in the world in 1950, developing countries occupied around 66.8%, and this figure will be reached 80.0% in 2050. Although developing countries are the home of the majority of the world elderly, the individual countries in developing countries have a lower proportion of older people, while developed countries have roughly 30% of older populations in their population structure. The results of the study also show two demographic variables, namely fertility and mortality, determined the changes in the proportion of the older population. The older population started to increase when the rate of fertility and mortality started to decline. The shift from high to low levels of fertility and mortality has been explained through the stages of demographic transition. Because developed countries are in the final stage of demographic transition, they are having a high proportion of elderly people. The demographic transition, creating population ageing, is a triumph of development in socioeconomic conditions of the community, and development in medical technology in the twentieth century.
