The Han nationality, also known as the Huaxia nationality, is a nation with a long history that has never been interrupted, and it is also the most populous nation in the world. According to relevant historical records, Yan Di tribe was defeated by Huangdi tribe in the Battle of Hanquan. After Yan Di Tribe was merged into Huangdi Tribe, Yanhuang Tribe gradually formed.
Han nationality, a nationality living in East Asia, belongs to the Mongolian race in East Asia and is the main nationality in several modern countries and regions. It accounts for 92% of the population in mainland China, 97% in Taiwan, 74% in Singapore and 23.4% in Malaysia.
Han nationality is distributed all over the world, with a total population of about 654.38+0.39 billion, accounting for about 654.38+0.8% of the world population. At present, it is the most populous country in the world. However, the fertility rate of Han nationality and some ethnic minorities in Chinese mainland is lower than the intergenerational replacement level.
Historical background:
On several occasions in history, the Han population migrated from the Yellow River basin and north of Huaihe River to the south of Yangtze River and Pearl River basin. When Qin unified the six countries, a large number of Kanto nobles moved to Guanzhong, and there were similar immigration activities in the Western Han Dynasty. However, the economic development at that time determined that the counties in the middle and lower reaches of the Yellow River were the most densely populated areas in China.
For example, if a county is divided into two parts, the northern part accounts for about 80% of the total registered population at that time, and the southern part accounts for about 20%. From the end of the Eastern Han Dynasty, people began to move south. By the end of the Western Jin Dynasty, people in the Yellow River basin moved south to the middle and lower reaches of the Yangtze River, the upper and middle reaches of the Yangtze River and the Hanshui River basin on a large scale.
After the Northern and Southern Dynasties, the population continued to move south, which made the population of the Yangtze River basin increase continuously, but it still did not change the situation that the population distribution in the north was more than that in the south. However, if the total population of southern counties in the late Sui Dynasty is compared with that in the Western Jin Dynasty, the population of the Yangtze River basin and Lingnan area has more than doubled.
In the late Tang Dynasty and the Five Dynasties, the northern population moved south again. At the end of the Northern Song Dynasty, Jin Bing committed crimes in the south, and there was a climax of the second population migration to the south. The population in the south has increased greatly, mainly concentrated in the Sichuan Basin and around Dongting Lake, Poyang Lake and Taihu Lake, as well as the Yangtze River and Pearl River Delta.
