China introduced its one-child policy in 1979 to curb population growth and improve living standards. It offered incentives for small families but also enforced strict penalties for violations through fines, loss of benefits, and even forced abortions. While the policy succeeded in significantly reducing birth rates, it has also had unintended social consequences like a gender imbalance favoring males, challenges supporting an aging population, and societal effects on family structure. The policy has since been relaxed but China still faces issues related to its aftermath.
