The natural population growth rate in North America is low, why is it growing much faster than that in Europe?

The key is the immigration factor. The relatively open immigration policy in North America makes this region become the region with the largest number of immigrants in the world, and the number of immigrants admitted to this region every year is much higher than that in other regions. The stricter immigration policy in Europe has greatly limited the number of immigrants.

The basic feature of China's population growth is "high and low" type, which quickly changed into "high and low" type after the founding of New China. The natural growth rate is generally around 20 ~ 23 ‰, while it is around 26‰ from 1962 to 1970 for nine consecutive years.

Among them, 33.33‰ of 1.963 is not only the highest peak over the years since the founding of New China, but also unparalleled in the whole history of China. During this period, the natural population growth in China was traditional.

Extended data:

Natural growth rate can also be expressed by the difference between birth rate and death rate (natural growth rate = birth rate-death rate). When the number of individuals born exceeds the number of dead individuals in a period of time, the natural growth rate is positive.

When the number of dead individuals exceeds the number of born individuals in a period of time, it is negative. Therefore, the level of natural growth depends on the relative level between birth rate and death rate, which is a comprehensive index reflecting population reproduction activities (population type).
