Using the 2000 census data, this paper examines patterns of duration of stay and the associated socio-demographic and economic characteristics for the migrant population in Guangdong Province. Logistic regression is used to identify the factors affecting duration of stay for the migrants. The paper concludes with a discussion of the fact that many of the migrants tend to permanently reside in Guangdong, and efforts need to be made in addressing social problems associated with this trend.
