China's family planning policies have included specific birth quotas as well as harsh enforcement of such quotas. Together, these elements constitute the population planning program of the People's Republic of China. China's program should not be confused with the family planning programs instituted in other countries, which were designed to encourage parents to have the number of children they desired—in China, the provision of contraception through family planning programs was subservient to a birth planning program under which the government designated how many births parents could have in order to control the size of its population.

The one-child policy 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.
