The Guangdong authorities published new guidelines on reform of the hukou (national household registration) system on July 6, 2015 which aims to grant local household registration to roughly 13 million migrant workers by 2020, allowing them to access public services—spanning housing, health-care, social security and education—that are typically reserved for urban residents. However, strict migration controls will remain in Guangdong’s largest cities, namely Shenzhen and Guangzhou. Among Guangdong's approx. 110 million residents, more than 24 million are migrants from other regions, while another 10.6 million have relocated within the province.
