Our Ageing World

For years, the major problem of world demography was thought to be the risk of over-population. Now, it's the fact that the global population is ageing fast.According to the United Nations, the number of people over 65 is set to double between now and 2050, to 1.6 billion people. And, at the same time, the birth rate in most of the world is falling, often sharply. This demographic shift comes with huge social and economic implications. What are they, and what can we do to cope with them?
