The list below outlines the distribution of the nationalities of China among provinces and province-level entities of the People's Republic of China (P.R.C.) according to the census of 2000. The provinces and province-level entities are listed by region. The classification of ethnic groups follows the official classification of the PRC. Some ethnic groups, for instance, Mosuo people, although classified as Nakhi, do not regard themselves as part of any of the 56 groups identified by the PRC government. Some scholars made hypothesis that they are descendants of Mongols.
