PIP: This preliminary study explored the impact on women of economic migration from rural to urban areas in China. Data were obtained from the 1990 census. The study focused on economic migration, which accounted for 29% of the reasons for moving. In some provinces such as Guangdong, economic reasons account for almost 60% of in-migrants. Interprovincial migration is primarily economic, followed by marriage, which varies widely by province. Migrants tend to assume occupations that are assigned by gender. Male migrants tend to outnumber female migrants, and women are left to farm. Where migration is gender balanced, the sex ratio in the sending area may be stable, but gender division within individual households is upset. Children may be tended by grandparents in rural areas, when their parents find work in cities. Migrants in urban areas do not have the same rights as permanent urban household registrants and cannot send their children to school or use free or low cost health care. Migrants keep in close contact with home villages. Urban migrants without permanent household registration status face the loss of welfare benefits in urban areas as well as the high cost of purchase of a permanent residence permit, social discrimination, stigma from mass media portrayals, and poor housing. Most rural-urban migration is circular. Female return migrants bring back cash remittances and new family roles and status. Rural migrants are exposed to new urban experiences that are retold in rural areas and that may pose difficulties in readjustment to the hardships of rural life. Urban fertility is delayed and lower than that of rural fertility.
