There are fewer and fewer Han people in Kashgar.

The influence of geographical and environmental factors, economic development and birth policy.

1. Geographical and environmental factors: Kashgar is located in the south of Xinjiang. It has been a region where ethnic minorities live in compact communities since ancient times, and the Han population mainly migrates.

2. Economic development: Kashgar is one of the least developed areas in China, and its development is slow due to the inconvenient transportation with the mainland.

3. Impact of birth policy: Xinjiang formulates family planning related policies according to national laws and regulations and local conditions. In the early 1970s, family planning was first implemented among the Han population. In the middle and late 1980s, ethnic minorities encouraged family planning. This differentiated birth policy is an important reason for the rapid growth of minority population in Xinjiang.
