Internal migration in the People's Republic of China is one of the most extensive in the world according to the International Labour Organization. This is because migrants in China are commonly members of a floating population, which refers primarily to migrants in China without local household registration status through the Chinese Hukou system. In general, rural-urban migrant most excluded from local educational resources, citywide social welfare programs and many jobs because of their lack of hukou status. Migrant workers are not necessarily rural workers; they can simply be people living in urban areas with rural household registration.
