The Chinese government introduced the One Child Policy in 1979 to address overpopulation, limiting urban couples to one child. Exceptions were made for rural families and ethnic minorities. The policy was enforced through fines and forced abortions. It succeeded in dramatically reducing birth rates but had negative effects like sex-selective abortion, abandonment of baby girls, and a future labor shortage. The policy has been relaxed in recent years to allow two children as China's population growth slows.
