What are the main factors affecting population distribution?

Population distribution is the result of many factors such as nature, society, economy and politics.

The influence of natural environment on population distribution is mainly reflected by latitude, topography and climate. Too high or too low latitude is not suitable for human life, and the restrictions in high latitude areas are particularly severe. Cold, frozen soil and insufficient light make the land undeveloped. So far, the northern boundary of human settlements is roughly consistent with the isotherm of 1 monthly average temperature of -20℃. The high terrain and great ups and downs also hinder human habitation.

Historical conditions are also a factor affecting population distribution. As a result of long-term population growth in history, the population of areas with early development and long history is generally relatively large. For example, the population density of the old continent is higher than that of the new continent.

Extended data:

The population distribution in China is extremely uneven in the horizontal direction, but it also shows a dense population in the plain area in the vertical direction. From the plain to the surrounding hills, plateaus and mountains, there is a law that the population decreases with the elevation of the terrain.

Due to historical reasons, so far, China's industrial production level is not high, the level of urbanization is low, and the proportion of urban population is small. Agriculture still dominates the economic activities of the people throughout the country. This is the current economic characteristics of China, and it is also a sign of the current level of productivity development. This situation has played a decisive role in the basic characteristics of population distribution in China.
