The origin of Chinese population is in the Yellow River basin, but now people resident all over China. What’s the main driving force that makes people move around ?
The population in North China exceeded that in south in early ancient times, but the pattern reversed with more population in south less in north nowadays. Why? When did it happen?
94.4% of the total population lives in the east, occupying 36% of the total area of China, whereas only 5.6% of the population lives in the west, taking up 64% of the land. What’s the reason for the uneven?
The phenomenon of 94% of the population living in east with 6% in the west began in about 1246 A.D. After that time, the proportion in the east has remained at around 94% to 95%.
The discrepancy of agricultural potential productivity in east-west have determined the final population distribution;
The climate change from 1230 to 1260 A.D. made the most contribution to the East-west pattern formation, which result in a warm and humid climate in the east leading to high agricultural density and a centralized population, and a cold and dry climate in the west causing a low and widely dispersed human population.
From 2 A.D. to 500A.D., the population’s center of gravity moved sharply toward the southeast, indicating that the population in the southeast increased .
From 900 A.D. to 1300 A.D., the population’s center of gravity continued moving toward the south, with only small changes in longitude. This reflects the stability of the population distribution in the east-west direction during this period.
After 1300 A.D., the population’s center of gravity shifted in both longitude and latitude in small range. Population distribution runs to stable.
