A noted American authority on urbanization and the household registration system in China reviews and clarifies factors leading to misunderstanding and misconceptions regarding the number of inhabitants of China's major cities. Principal sources of confusion linked to reliance on official statistical sources are the multi-layered meanings of the term "city" and, consequently, simultaneous publication and use of a multitude of official population statistics for the country's "cities." Other complicating factors analyzed by the author include the effects of the Chinese hukou (household registration) system and the rapid rate of urban growth and change over the last three decades. Systematic population and per capita GDP data for the years 2000 and 2005, all based on the multiple boundaries and systems for five major cities (Beijing, Shanghai, Chongqing, Guangzhou, and Shenzhen), are collected to illustrate both the countrywide situation and specific cases. Also included is a critique of several studies and popular accounts of Chinese cities to highlight misstatements and areas of misunderstanding based on inappropriate use of statistical data.

Key words: China, cities, mega-cities, urban population statistics, hukou system, household registration, per capita GDP, Beijing, Shanghai, Chongqing, Guangzhou, Shenzhen.
