Chongqing

The International Herald Tribune (April 5) reports that Chongqing in
Sichuan province has 4.1 million people living in the city proper
but when its surrounding areas are considered, it's home to more
than 31 million, which makes it the largest population center in
China. Chongqing's annual GDP per capita is $1,363, which isn't
particularly impressive when you think about it. Last year, U.S. GDP
per capita was $43,500.
