Population changes and their causes after the founding of New China.

When the Republic of China was founded, the population of China was about 400 million. By 1949, the population of China was about 400 million to 500 million (there was no national population survey during the Republic of China, only approximate data). In more than 30 years, the population of China has increased by about 1 100 million.

1953, the first national census of new China showed that the population of China at that time was 60 1938035. 1982 When family planning was officially implemented, the population of China was1031882511. In about twenty-nine years, the population of China has increased by 429,944,476.

It can be said that at about the same time, the population growth of New China was four to five times that of the Republic of China. There is a view that the reason for this situation is that the birth rate has greatly increased due to the implementation of the birth-encouraging policy in New China, so the population has grown on a large scale.

According to statistics, the average birth rate in the past 30 years of the Republic of China was about 3.5% to 3.8%, while the average birth rate before the implementation of family planning in New China was 3.6%. This shows that the birth rate in New China has not changed significantly compared with the period of the Republic of China, which means that the view that "the rapid population growth in New China is due to the increase in birth rate" is completely out of line with history.

We should know that the rapid growth of population is not only affected by the birth rate, but also by the death rate.

After the founding of People's Republic of China (PRC), due to the improvement of people's living standards and medical and health conditions, the mortality rate dropped significantly, and the population of China increased rapidly.

Historical development:

Historically, the population of China has always accounted for a large proportion of the world population. From 65438 to 0850, the population of China was about 430 million, accounting for 34% of the world population. Due to the war and other reasons, the population growth in China is slow, from 1850 to 1950. At the end of 1949, the population of mainland China was 541670,000, accounting for 22% of the world population.

Since 1950, the population of all countries in the world has increased rapidly due to the development of production and the improvement of life expectancy. By the end of 1990, the population of China had reached 165438+4333 million, but its proportion in the world population remained at about 22%.

As early as 1962, the Central Committee and the State Council issued instructions to seriously promote family planning. From 65438 to 0990, with the continuous strengthening of family planning, the fertility rate in China dropped below the replacement level. Due to the demographic structure, the total population of China keeps growing, but its proportion in the world is decreasing year by year, and the aging degree is deepening.
