children a family can have, immense social pressures are placed upon women. Women are mostly blamed when giving birth to a girl. Women were subjected to forced abortions if they appear to be having a girl. This situation led to higher female infanticide rates and female deaths in China. Other Asian regions also have higher than average ratios, including Taiwan (110:100), which does not have a family planning policy. Many studies have explored the reason for the gender-based birthrate disparity in China as well as other countries. A study in 1990 attributed the high preponderance of reported male births in mainland China to four main causes: diseases which affect females more severely than males; the result of widespread under-reporting of female births; the illegal practice of sex-selective abortion made possible by the widespread availability of ultrasound; and finally, acts of child abandonment and infanticide. Iron Fist Campaign According to reports by Amnesty International, family planning officials in Puning City, Guangdong Province, launched the Iron Fist Campaign in April 2010. This campaign targeted individuals for sterilization in an attempt to control population growth. The targeted individuals were asked to go to governmental clinics where they would be sterilized. If they refused the procedure, then they put their families at risk for detainment. 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. Property ownership In current-day China, women enjoy legal equal rights to property, but in practice, these rights are often difficult to realize. Chinese women have historically held little rights to private property, both by societal customs and by law. In imperial China (before 1911 C.E.), family households held property collectively, rather than as individual members of the household. This property customarily belonged to the family ancestral clan, with legal control belonging to the family head, or the eldest male. Ancestry in imperial China was patrilineal, or passed through the male, and women could not share in the family property. Upon
