The one child policy, a part of the family planning policy, was a population planning policy of China. It was introduced in 1979 and began to be formally phased out in 2015. The policy allowed many exceptions and ethnic minorities were exempt. For example in 2007, 36% of China's population was subject to a strict one-child restriction, with an additional 53% being allowed to have a second child if the first child was a girl. Provincial governments imposed fines for violations, and the local and national governments created commissions to raise awareness and carry out registration and inspection work. In addition to fines, the policy was implemented through surgically implanted contraceptive devices or sterilizations, which affected over 400 million women between 1980 and 2014.

According to the Chinese government, 400 million births were prevented. This claim has been called "false" by scholars, because "three-quarters of the decline in fertility since 1970 occurred before the launching of the one-child policy; and most of the further decline in fertility since 1980 can be attributed to economic development." Thailand and Iran, along with the Indian states of Kerala and Tamil Nadu, have had similar declines of fertility without a one-child policy. Although 76% of Chinese people supported the policy in a 2008 survey, it was controversial outside of China.

On October 29, 2015, it was reported that the existing law would be changed to a two-child policy, citing a statement from the Communist Party of China. The new law became effective on January 1, 2016, following its passage in the standing committee of the National People's Congress on December 27, 2015.

During the period of Mao Zedong's leadership in China, the birth rate fell from 37 per thousand to 20 per thousand. Infant mortality declined from 227 per thousand births in 1949 to 53 per thousand in 1981, and life expectancy dramatically increased from around 35 years in 1948 to 66 years in 1976. Until the 1960s, the government encouraged families to have as many children as possible because of Mao's belief that population growth empowered the country, preventing the emergence of family planning programs earlier in China's development. The population grew from around 540 million in 1949 to 940 million in 1976. Beginning in 1970, citizens were encouraged to marry at later ages and have only two children.
