What are the characteristics of the world population distribution?

The main characteristics of world population distribution are:

1, unbalanced

The biggest feature of population distribution is imbalance. As far as the world is concerned, only 7% of the earth's land area is inhabited by 70% of the world's population; More than 90% of the world's population is concentrated in less than 10% of the land; On the mainland, 35% ~ 40% of the land is basically uninhabited.

2. Distribution regularity

The population is distributed horizontally, mainly in the northern hemisphere, where 90% of the earth's population lives, while only 65,438+00% in the southern hemisphere. In the northern hemisphere, the population is mostly concentrated in temperate and subtropical areas between 20 and 60 north latitude.

Population distribution also tends to be concentrated in coastal areas. The population is distributed in the vertical direction, and a large number of them are concentrated at relatively low altitudes, while the population at high altitudes is relatively sparse.

3. Time lag

Population distribution often lags behind the development of productive forces and the transfer of economic centers. The reason is that the change of population distribution depends on the time cumulative effect of natural growth rate and net migration rate, and the speed is relatively slow. Only in the newly developed areas with small population base can the immigration factor produce obvious results immediately.

Extended data:

The population density distribution in different parts of the world is uneven. The Asian monsoon region, led by East Asia, Northeast Asia and South Asia, the European Plain and the eastern part of North America are the most densely populated places in the world. Because there are many valleys and lowlands in these places, it is easy to produce food and the climate is suitable for human habitation.

In polar regions, deserts, mountains, plateaus, tropical rainforests and other places, the population is very sparse because of cold, drought, steep terrain, humidity and other factors that are not suitable for human habitation.
