What are the characteristics of the world population distribution?

Characteristics of world population distribution:

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. 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. The study on the distribution characteristics and formation conditions of population (phenomenon) in the world, countries and regions almost constitutes the whole content of population geography.

Factors affecting population distribution

1. Water resources: the areas along the river and the lake are densely populated; The drier the area, the greater the influence of water on population distribution. In the arid area of northwest China, the population is concentrated in the oasis rich in water resources.

2. Soil: more indirectly obtained through agricultural development. (The fertile black soil in Northeast China has a high population distribution)

3. Economic factors: the population in economically developed areas is large and dense (the urban area is dominated by secondary and tertiary industries with dense population); The population in economically backward areas is small and scattered. (decisive influence)
