Why is the population of Europe less than that of Asia since ancient times?

This reflects the cultural differences between East and West. Orientals, mainly farming economy, rely on labor, so every household has a large population as its first priority. For example, in ancient China, when you married a daughter-in-law, you wanted to marry a woman with a big ass who could have children. In this way, the population of the East grew rapidly. If it weren't for the war, the population of Asia would be terrible.

Comparatively speaking, Europeans rely more on the marine economy and pay less attention to the population than the farming economy. In addition, Europeans advocate self-esteem, and the requirement for sex is only self-experience, and there is no thinking concept of passing on the family. In this way, the fertility desire of Europeans is much worse. This is the main reason why the population of Europe is smaller than that of Asia.
