The greying of the prosperous parts of the world has long been forseen. Much less well know is the fact that well-off countries are far from alone in facing the prospect of an agening population.
As more amd more Indians and Chinese escape from poverty, they too will have longer life spans.
By 2050 the percentage of the Indian population over 80 will have risen five-fold, and the same segment in China will have gone up six times. The reasons for such increase are
1. peoples general health is better
2. childbirth is safer and malaria more treatable.
By 2050 about 80% of all deaths in the world will occur in people who are older than 60.
