China's One Child Policy

For centuries, China has had the world’s largest population, although it will soon lose that title to India. When Mao Zedong and his colleagues seized national power in 1949, they were not sure how many Chinese there were (the first modern census was not conducted until 1953), and Mao initially argued that having a large and rapidly increasing population was a blessing for China, rather than a curse. However, the challenges of managing such a large and poor country soon changed the official view, and during some intervals in the 1950s and 1960s, China carried out voluntary family planning campaigns to try to reduce the birth rate. However, those campaigns were largely ineffective, with the only notable decline in fertility during those decades produced by the Great Leap Forward–induced mass famine of 1959–1961, not family planning efforts. As of 1970 the projected number of babies the average Chinese mother would have in her lifetime (termed the total fertility rate [TFR]) was still close to six. (China’s cities, where less than 20 percent of the population lived at the time, is an exception to these generalizations, with the 1960s family planning campaign playing some role in reducing the urban TFR in 1970 to 3.2.) Early in the 1970s, when Mao was still in charge (he died in 1976), China made a dramatic shift from voluntary family planning to mandatory birth limits under the slogan, “later (marriage ages), longer (birth intervals), and fewer” (births—no more than two babies for urban families and three for rural families). The “later, longer, fewer” campaign was enforced very strictly, using many of the coercive measures that later became notorious during the one-child campaign, and China’s fertility rate fell dramatically, to less than three per mother by the end of the decade. Despite this success, in 1980 the Chinese Communist Party (CCP) launched an even more demanding and coercive campaign that attempted for the next thirty-five years to limit Chinese families to having only one child. The fertility rate actually went up in the early 1980s but then began to decline again, reaching sub-replacement fertility (TFR = 2.1) by the early 1990s. Most experts estimated that China’s TFR fluctuated in the 1.4 to 1.6 range between 2000 and 2015, although some analysts have calculated slightly higher estimates. (The subsequent decline in births, discussed in the final section of this essay, reduced China’s TFR in 2020 to 1.3 according to the census that year, approaching the very low fertility of the richest countries in East Asia.) The CCP in late 2015 decided to end the one-child limit, with Chinese families since January 1, 2016 allowed to have two children (raised to three children in 2021). Debates about the controversial one-child policy have spawned a large literature that examines many issues, including the reasons the CCP launched this campaign, how effective it was in reducing birth rates further, what human rights abuses resulted, how child-rearing and children have been affected, and in what ways Chinese society and the people of China have benefited or have been harmed by the demographic distortions produced by mandatory, state-enforced birth limits.
