Chongming District ( pronunciation ) is northernmost district of the provincial-level municipality of Shanghai in China. Chongming consists of three low-lying inhabited alluvial islands at the mouth of the Yangtze north of the Shanghai peninsula: Chongming, Changxing, and Hengsha. Following its massive expansion in the 20th century, Chongming is now the 2nd-largest island administered by the People's Republic of China and the 3rd-largest in Greater China, after Taiwan and Hainan. Chongming does not, however, administer all of the Chongming: owing to its continual expansion from sediment deposited by the Yangtze, it has merged with formerly separate islands and now includes Jiangsu province's pene-exclave townships of Haiyong and Qilong. Chongming proper covers an area of 1,411 kilometers (877 mi) and had a population of 704 000 at the time of the 2010 Chinese census.
