What is the change of population in Sichuan history?

From 3 16 BC to 2 AD, the population of Sichuan increased from 50,000 to 35 1 10,000.

At the end of the Song Dynasty, Sichuan had the most tenacious resistance to the Mongolian and Yuan armies, and it was also retaliated by the Yuan armies, and its population plummeted from100000 to 600000.

At the end of Yuan Dynasty and the beginning of Ming Dynasty, the Ming Dynasty organized immigrants again, and Sichuan was almost replaced by Hubei and Hunan people, which was quite different from the original northern immigrants.

However, at the end of the Ming Dynasty, Sichuan was not prosperous, and the peak of population development was only 365,438+10,000.

Since Shen Jianian (1644) in the late Ming Dynasty, Sichuan has also experienced the most tragic scene in history: 365,438+10,000 people are constantly resisting and killing.

There are only 80 thousand students left in middle school.

During the period from Shunzhi to Jiaqing, Manchu organized a large-scale migration to Sichuan, which is the famous story of "Huguang filling Sichuan".

In more than 100 years, it flooded every corner of Sichuan, and it grew to 28 million people in Jiaqing years.
