Who enforced the rule of the one child policy?

The one-child policy in China was enforced by the National Population and Family Planning Commission, along with local government authorities. These agencies implemented the policy through various means, including monitoring births, providing incentives for compliance, and imposing penalties for violations. Enforcement often involved community workers who tracked family planning practices at the grassroots level. Despite its official status, the policy faced significant challenges and criticism, leading to its eventual relaxation in 2015.
