Chongquing is the largest and most populous of the People's
Republic of
China's
four provincial-level municipalities, and the only
one in the less densely populated
western half of China. Formerly (until 14
March 1997) a provincial city within
Sichuan Province, the municipality of
Chongqing has a registered population of 31,442,300 (2005), with most of them living outside the urban
area of Chongqing proper, over hundreds of
square kilometres of
farmland. The population of the urban area of Chongqing proper was 4.1 million in 2005.
The municipal abbreviation, 渝 (Yú), was approved by the State
Council on 18
April 1997.
Chongqing was also a municipality of the old
Republic of
China. Its abbreviated
name is derived from the old name of a part of the Jialing River that runs through Chongqing and feeds the Yangtze River.
