AGEING GIANT

Before the end of the present century the population of China - currently around 1.4 billion - is forecast to drop to around half that level as a major and unprecedented demographic crisis begins to bite. Its working-age population has already stopped growing and is now well into a process of contraction. Increasing longevity means that by the 2050s there will be more than 400 million Chinese citizens over the age of 65 - with little provision for their care in a society where a single child is now the norm. The ratio of the retired to those working is steadily rising, putting pressure on families and the public finances. Years of preference for a male child has seen the creation of a skewed sex ratio at birth that already guarantees well over 50 million surplus adult males, unmarried and unhappy, in the coming years. This is more than the entire male population of Germany. The state has previously sought to impose its will on reproduction, but Chinese families experienced a sharply reduced birthrate even before the introduction of the notorious one-child policy.
