China will have an urban population of 1 billion by 2030 according to McKinsey forecast & UN data (2009-2010).
Also by 2030, China will have 221 cities with more than 1 million people. During this period, 400 million Chinese will move to urban areas, more than the population of the US and Brazil combined. (Source: Foreign Policy, August 2010.)
China’s Academy of Sciences estimated that for every 1% increase in urbanization, China can expect a 1.6% increase in the contribution made by domestic demand to China’s GDP.
