Ageing and development
We all know that we are living through a time of global population growth unprecedented in human history. The number of people in the world has doubled since 1970, and will grow further, from 7 to 10 billion, by 2050.
But less well-known is the fact that the world is ageing as well as growing. There are currently 928 million older people in the world, and by 2050 this number will have reached more than 2 billion – 21 per cent of the world’s population. And most will live in developing countries.
