The one-child policy (Chinese: 一孩政策; pinyin: yī hái zhèngcè) was a population planning initiative in China implemented between 1979 and 2015 to curb the country's population growth by restricting many families to a single child. The program had wide-ranging social, cultural, economic, and demographic effects, although the contribution of one-child restrictions to the broader program has been the subject of controversy. Its efficacy in reducing birth rates and defensibility from a human rights perspective have been subjects of controversy.
China's family planning policies began to be shaped by fears of overpopulation in the 1970s, and officials raised the age of marriage and called for fewer and more broadly spaced births. A near-universal one-child limit was imposed in 1980 and written into the country's constitution in 1982. Numerous exceptions were established over time, and by 1984, only about 35.4% of the population was subject to the original restriction of the policy. In the mid-1980s, rural parents were allowed to have a second child if the first was a daughter. It also allowed exceptions for some other groups, including ethnic minorities under 10 million people. In 2015, the government raised the limit to two children, and in May 2021 to three. In July 2021, it removed all limits, shortly after implementing financial incentives to encourage individuals to have additional children.
