In 1970, Chinese women were having an average of nearly six children each. Only nine years later, this figure had dropped to an average of 2.7 children per woman. This steep fertility decline was achieved before the Chinese government introduced the infamous one-child policy. Today, at 1.5 children per woman, the fertility rate in China is one of the lowest in the world. Such a low fertility level leads to extreme population aging–expansion of the proportion of the elderly in a population, with relatively few children to grow up and care for their aging parents and few workers to pay for social services or drive economic growth. China’s birth-control policies are now largely relaxed, but new programs are needed to provide healthcare and support for the growing elderly population and to encourage young people to have children. It will be increasingly difficult to fund such programs, however, as China’s unprecedented pace of economic growth inevitably slows down.
China’s Fertility Decline
Most of China’s fertility decline took place in the 1970s, before the government launched its one-child policy in 1980 (see Figure 1). During the 1980s, fertility fluctuated, for the most part above the replacement level of 2.1 births per woman, which would maintain a constant population size. Then in the early 1990s, fertility declined to below-replacement level, and since then it has further declined to around 1.5 children per woman today. If very low birth rates persist, eventually the population starts to shrink, and it can shrink very quickly. Today’s low fertility could lead to a decline in China’s population by as many as 600 million people by the end of the 21st century.
