The Iron Fist Campaign lasted for 20 days and targeted 9,559 individuals. Approximately 50 percent consented and 1,377 relatives of targeted couples were detained. Family planning officials defended the Iron Fist Campaign, asserting that the large population of migrant workers in Puning misunderstood the One-child policy and therefore had not complied with family planning regulations. In an attempt to standardize family planning policies across all of China, the Population and Family Planning Law of 2002 was implemented, which protects individual rights and bans the usage of coercion or detainment.
