According to the data in 2021, the total urban resident population of Hangzhou was up to 9,930,000. Calculated based on the population growth rate and layout of Hangzhou in recent years, the total population may exceed 10,000,000, reaching the standard of the megacity, second only to Shanghai in the Yangtze River Delta region.

In the eyes of urbanologists, China's megacities have the similar meaning to the internationally defined "cosmopolises". Such cities have powerful economic and industrial strength, with unique urban cultural atmosphere, which promotes the development of the region and even the whole country.

In the process of population growth, Hangzhou will continue to optimize the urban environment that is livable and enjoyable.
