The 2010 Census counted 234,829 residents from Hong Kong, 21,201 residents from Macao, 170,283 residents from Taiwan, and 593,832 residents from other locations, totaling 1,020,145 residents. Populations often vary because the cities do not have city limits as we think of them. At times they include just the city core and at other times all territory the city controls. For example Chongqing controls some 30 million.
