1, the growth is slow.
From 60 million in AD 2 to 430 million in 1850, the total number has only increased seven times, and the average annual growth rate is only about 1‰.
2. ups and downs.
The sustained growth in some periods and the sharp decline in some years alternate.
For example, in the early Western Han Dynasty, the Tang Dynasty in the early 8th century, the Northern Song Dynasty in the1/century, and the Qing Dynasty in the18th century, the average annual population growth rate in the past decades to more than one hundred years can reach 7 ‰-/kloc-0 ‰.
There may be a higher average annual growth rate in the recovery stage.
When the population drops sharply, it can be reduced by more than 50% in one or two decades, and the annual negative growth can be as high as 50 ‰- 100 ‰.
3. Population development is staged.
The first stage, from self-employment to the beginning of the year, reached 60 million.
The second stage, from the Eastern Han Dynasty to the prosperous Tang Dynasty in the middle of the 8th century, increased to nearly 90 million.
In the third stage, from the middle Tang Dynasty to the Five Dynasties, 1 broke through at the beginning of the 2nd century1billion,10/0.2 billion at the beginning of the 3rd century.
The fourth stage, from the end of Song Dynasty to the beginning of Yuan Dynasty to17th century Ming Dynasty, totaled more than 200 million.
In the fifth stage, the population declined in the late Ming and early Qing dynasties, and/kloc-0 recovered in the early 8th century, reaching a new peak of 430 million in the middle of the 9th century.
In the sixth stage, after nearly a hundred years of decline and low growth, high-speed growth began to appear in the 1950 s. Although the speed slowed down after the 1970s, it still exceeded the 65.438+0.2 billion mark in recent years.
The doubling time of the second and third stages is 1300 years, the fourth stage is 500 years, the fifth stage is less than 250 years, and the sixth stage is only 40 years.
4. The class imbalance of population growth.
Because of political, economic and cultural privileges and better living conditions, the population growth rate of the landlord class is always higher than that of the peasants and the whole population, so its proportion in the total population will be higher and higher with the continuation of the dynasty.
5. Racial imbalance in population growth.
Mainly manifested in the growth of Han and agricultural nationalities is generally higher than that of non-Han and nomadic nationalities, so the proportion of Han and agricultural nationalities in the total population is getting higher and higher.
In addition to the Han nationality, the population growth of other ethnic groups is also uneven.
