Demographics
As of July 2006, there are 1,313,973,713 people in the PRC. About 20.8% (male 145,461,833; female 128,445,739) are 14 years old or younger, 71.4% (male 482,439,115; female 455,960,489) are between 15 and 64 years old, and 7.7% (male 48,562,635; female 53,103,902) are over 65 years old. The population growth rate for 2006 is 0.59%. The PRC officially recognizes 56 distinct ethnic groups, the largest of which are the Han Chinese, who constitute about 91.9% of the total population. Large ethnic minorities include the Zhuang (16 million), Manchu (10 million), Hui (9 million), Miao (8 million), Uyghur (7 million), Yi (7 million), Tujia (5.75 million), Mongolians (5 million), Tibetans (5 million), Buyi (3 million), and Koreans (2 million).
In the past decade, China's cities expanded at an average rate of 10% annually. The country's urbanization rate increased from 17.4% to 41.8% between 1978 and 2005, a scale unprecedented in human history. 80 to 120 million migrant workers work part-time in the major cities and return home to the countryside periodically with their earnings.
Today, the People's Republic of China has dozens of major cities with one million or more long-term residents, including the three global cities of Beijing, Hong Kong, and Shanghai. Major cities in China play key roles in national and regional identity, culture and economics.
Largest cities
The figures below are the 2001 estimates for the ten largest urban populations within administrative city limits; a different ranking exists when considering the total municipal populations (which includes suburban and rural populations). The large floating populations of migrant workers make conducting censuses in urban areas difficult; the figures below do not include the floating population, only long-term residents.
