Noun
one-child policy (plural one-child policies)
(historical) A policy of population control in China, whereby a married couple is allowed only one child.
China's one-child policy was born in 1980, after years of less severe measures to discourage births. The Communist Party promised that the policy would be temporary. Barbara Demick
Over the years, so many exceptions and amendments were made to China's one-child policy that it was hard to pinpoint a moment to pronounce it dead. Barbara Demick
