The Song Dynasty was divided into two stages: the Northern Song Dynasty and the Southern Song Dynasty. During the Northern Song Dynasty, the land area was about 2.8 million square kilometers and the population was about 654.38+300 million. During the Southern Song Dynasty, the largest land area was about 2 million square kilometers and the largest population was about 80 million.

From this, we can calculate the population of "one square kilometer" in each dynasty, which is 10 in Han Dynasty, 1 1 in Sui Dynasty, 7 in Tang Dynasty, 12 in Ming Dynasty, 30 in Qing Dynasty, 46 in Northern Song Dynasty and 40 in Southern Song Dynasty.

brief introduction

The population of Song Dynasty was the most prosperous. In ancient times, population was productivity, so all previous dynasties encouraged fertility. In addition to war, famine and other factors, the output of grain is also a major cause of population bottleneck.

In the Song Dynasty, Confucianism revived and Zhu Cheng Neo-Confucianism appeared. Science and technology developed rapidly, politics was enlightened, and there was no serious eunuch dictatorship and warlord regime. The number and scale of mutiny and civil strife are relatively small in the history of China. The population of Zhancheng Rice increased rapidly in the Northern Song Dynasty, from 3,765,438+million in 1980 to124 to1260,000.
