Population
A 2015 report concluded that, if taken as a single urban area, the zone is the largest such area in the world in both area and population, with a population exceeding 75 million inhabitants. The population density of the Pearl River Delta region is quite high in China and even in the world. Its population growth mainly comes from immigrants, and the natural growth rate of the population does not have a major impact on population growth. The World Bank report uses satellite and geospatial information analysis technology to assess the urbanization progress in the eastern region of Asia, including Northeast Asia and Southeast Asia. It shows that as of 2010, the Pearl River Delta urban area, including Guangzhou, Shenzhen, Foshan and Dongguan, has a population of about 42 million, which is more than the total population of countries such as Argentina, Canada or Malaysia, and has surpassed the Tokyo area of Japan, becoming the world's largest urban area. ==See also==
