There are more than 225 million rural-to-urban migrant workers, and some 20 million migrant children in Chinese cities. Because of policies related to the household registration (hukou) system, migrant students are not allowed a public high school education in the cities, so their urban education stops abruptly at the end of middle school. This book investigates the post-middle school education and labor market decisions of migrant students in Beijing and Shanghai, and provides a glimpse into the future of a crucial link in China’s development. The stories of how these migrant students seek upward mobility and urban citizenship also reveal one of the most intricate structural inequalities in China today.
