The issue of ageing is shared by both developed and developing countries. The proportion of older persons in less developed countries is expected to increase from 8 per cent in 2010 to 20 per cent by 2050, while the proportion of children will decrease from 29 to 20 per cent. The number of older women living in less developed regions will increase by 600 million within the period 2010 to 2050. This demographic shift presents major challenges for developing countries. The ageing of society is a well-established trend and a significant feature in most developed countries.
