Internal Migration and the Health of Middle-Aged and Older Persons in China: The Healthy Migrant Effect Reconsidered

This study investigates associations between internal migration and health among middle-aged and older adults in China, including variations associated with type of migration (rural-to-urban, urban-to-rural, rural-to-rural, urban-to-urban). Data were drawn from China’s Health and Retirement Longitudinal Study (2011, 2013, 2015). Lagged panel and fixed-effect regression models address associations between migration and health outcomes (self-rated health, depression) while controlling for pre-migration and post-migration selection effects. The results reveal the positive implications of rural-to-urban migration for the self-rated health of middle-aged but not older adults. They also point to the positive effects of migration within and to rural areas for the self-rated and mental health of older adults. Overall, although migration may be beneficial to the health of internal migrants in China, complexities associated with age, type of migration, and the health outcome involved need to be taken into account.
