Top Questions What is the one-child policy?The one-child policy was a program in China that limited most Chinese families to one child each. It was implemented nationwide by the Chinese government in 1980, and it ended in 2016. The policy was enacted to address the growth rate of the country’s population, which the government viewed as being too rapid. It was enforced by a variety of methods, including financial incentives for families in compliance, contraceptives, forced sterilizations, and forced abortions.
When was the one-child policy introduced?September 25, 1980, is often cited as the official start of China’s one-child policy, although attempts to curb the number of children in a family existed prior to that. Birth control and family planning had been promoted from 1949. A voluntary program introduced in 1978 encouraged families to have only one or two children. In 1979 there was a push for families to limit themselves to one child, but that was not evenly enforced across China. The Chinese government issued a letter on September 25, 1980, that called for nationwide adherence to the one-child policy.
Why is the one-child policy controversial?China’s one-child policy was controversial because it was a radical intervention by government in the reproductive lives of citizens, because of how it was enforced, and because of some of its consequences. Although some of the government’s enforcement methods were comparatively mild, such as providing contraceptives, millions of Chinese had to endure methods such as forced sterilizations and forced abortions. Long-term consequences of the policy included a substantially greater number of males than females in China and a shrinking workforce.
When did the one-child policy end?The end of China’s one-child policy was announced in late 2015, and it formally ended in 2016. Beginning in 2016, the Chinese government allowed all families to have two children, and in 2021 all married couples were permitted to have as many as three children.
What are the consequences of the one-child policy?There have been many consequences to China’s one-child policy. The country’s fertility rate and birth rate both decreased after 1980; the Chinese government estimated that some 400 million births had been prevented. Because sons were generally favoured over daughters, the sex ratio in China became skewed toward men, and there was a rise in the number of abortions of female fetuses along with an increase in the number of female babies killed or placed in orphanages.
After the one-child policy ended in 2016, China’s birth and fertility rates remained low, leaving the country with a population that was aging rapidly and a workforce that was shrinking. With data from China’s 2020 census highlighting an impending demographic and economic crisis, the Chinese government announced in 2021 that married couples would be allowed to have as many as three children.
one-child policy, official program initiated in the late 1970s and early ’80s by the central government of China, the purpose of which was to limit the great majority of family units in the country to one child each. The rationale for implementing the policy was to reduce the growth rate of China’s enormous population. It was announced in late 2015 that the program was to end in early 2016.
China began promoting the use of birth control and family planning with the establishment of the People’s Republic in 1949, though such efforts remained sporadic and voluntary until after the death of Mao Zedong in 1976. By the late 1970s China’s population was rapidly approaching the one-billion mark, and the country’s new pragmatic leadership headed by Deng Xiaoping was beginning to give serious consideration to curbing what had become a rapid population growth rate. A voluntary program was announced in late 1978 that encouraged families to have no more than two children, one child being preferable. In 1979 demand grew for making the limit one child per family. However, that stricter requirement was then applied unevenly across the country among the provinces, and by 1980 the central government sought to standardize the one-child policy nationwide. On September 25, 1980, a public letter—published by the Central Committee of the Chinese Communist Party to the party membership—called upon all to adhere to the one-child policy, and that date has often been cited as the policy’s “official” start date.
The program was intended to be applied universally, although exceptions were made—e.g., parents within some ethnic minority groups or those whose firstborn was handicapped were allowed to have more than one child. It was implemented more effectively in urban environments, where much of the population consisted of small nuclear families who were more willing to comply with the policy, than in rural areas, with their traditional agrarian extended families that resisted the one-child restriction. In addition, enforcement of the policy was somewhat uneven over time, generally being strongest in cities and more lenient in the countryside. Methods of enforcement included making various contraceptive methods widely available, offering financial incentives and preferential employment opportunities for those who complied, imposing sanctions (economic or otherwise) against those who violated the policy, and, at times (notably the early 1980s), invoking stronger measures such as forced abortions and sterilizations (the latter primarily of women).
The result of the policy was a general reduction in China’s fertility and birth rates after 1980, with the fertility rate declining and dropping below two children per woman in the mid-1990s. Those gains were offset to some degree by a similar drop in the death rate and a rise in life expectancy, but China’s overall rate of natural increase declined.
