Ethnic distribution areas in China:

China has a long history, and all ethnic groups have formed their own national culture and customs. The distribution of ethnic groups is characterized by mixed residence, small settlement and staggered residence. There are ethnic minorities living in Han areas, and there are also Han people living in ethnic minority areas. This distribution pattern is formed by the interaction and flow between ethnic groups in the long-term historical development process.

Although the population of ethnic minorities in China is small, they are widely distributed. All provinces, autonomous regions and municipalities directly under the Central Government are inhabited by ethnic minorities, and most county-level units are inhabited by more than two ethnic minorities.

Ethnic minorities in China are mainly distributed in Inner Mongolia, Xinjiang, Ningxia, Guangxi, Tibet, Yunnan, Guizhou, Qinghai, Sichuan, Gansu, Heilongjiang, Liaoning, Jilin, Hunan, Hubei, Hainan, Taiwan Province and Chongqing. China is the country with the largest ethnic composition in the world, with 25 ethnic groups.
