What are the distribution characteristics of all ethnic groups in China?

The overall characteristics of China minority areas are as follows: 1. The territory is vast and the population is sparse. Many ethnic minorities live in mountainous areas, plateaus, pastoral areas and forest areas. Second, the product resources are abundant. It plays an extremely important role in China's modernization. Third, most of them are located in China's frontiers and belong to national defense. Population changes caused by many ethnic migrations, immigration frontier defense and dynasty changes in history. The ethnic distribution in China has formed a situation in which all ethnic groups live together alternately. Some ethnic minorities have one or several inhabited areas scattered all over the country. About10 million people are scattered in towns and villages in various provinces and cities across the country. In economic, political and cultural life, ethnic minorities not only influence each other, but also have close ties with the Han nationality.

Most of the ethnic minorities in China are located in the border areas, shouldering the dual tasks of defending and building the border areas. Ethnic minority areas occupy a very important position in politics, national defense, economy and foreign relations.

We say that ethnic minorities mainly live in border areas and call them ethnic minority areas. However, not all the residents in the main ethnic minority areas are ethnic minorities, and many Han people live together. In areas where ethnic minorities live in concentrated communities, most ethnic minorities live together or cross-live with the Han nationality. According to 1990 national census, in Inner Mongolia, Guangxi and Ningxia, the population of Han nationality exceeds that of ethnic minorities. In Xinjiang Uygur Autonomous Region, although the population of Han nationality does not exceed the population of ethnic minorities, it is also close to 40% of the population of the whole region. Moreover, in ethnic minority areas, not only the main local ethnic minorities live together with the Han nationality, but also some other ethnic minorities. For example, in Xinjiang Uygur Autonomous Region, apart from Uighurs and Hans, there are more than a dozen ethnic minorities living together. Yunnan province is a place where many nationalities live together, and there are more than 20 nationalities in the province. There are few ethnic groups in Xizang Autonomous Region, but there are still Han, Hui, Menba, Barrow and other ethnic groups living together with Tibetans. Similarly, there are many ethnic minorities living in areas where the Han nationality is concentrated. For example, although Shanghai is dominated by Han people, there are also 37 ethnic minorities. As far as the whole country is concerned, almost no city or county in China is ethnically homogeneous. Therefore, the distinctive feature of the distribution of ethnic groups in China is that the Han nationality is the main body of ethnic groups living together and living in small communities.
