Why is the population of Suzhou more than that of Nanjing?

The population of Suzhou actually refers to the population of Suzhou, including 1 prefecture-level city and 5 county-level cities. There are many low-end processing and manufacturing industries, which have attracted nearly 6 million rural people to find jobs and the living cost is low, so the resident population has increased. The registered population of Suzhou (including county-level cities) is basically the same as that of Nanjing, mainly because there are millions more migrant workers. In addition, as far as the two cities are concerned (excluding escrow counties), the population of Nanjing is about 2 million more than that of Suzhou.

If the population of Suzhou is larger than that of Nanjing, then Suzhou is a big city, which will make people laugh, because it is not only a population problem, but also the development and core of population quality, science, education, culture and health, and traffic conditions.
