Chongqing's Population Increases over 3.2 mln in Past Decade


Chongqing- The population of Chongqing Municipality in southwestern China increased by 3.208 million from 2010 to 2020, according to a municipal press conference Thursday.

The Information Office of Chongqing Municipal People’s Government held a press conference on May 13th, 2021, where leading officials in the Seventh National Population Census announced results and preliminary analysis for Chongqing Municipality.

The main purpose is to comprehensively analyze China’s population in terms of number, structure, and distribution and provide accurate statistical information support for improved development strategies and policy systems, the formulation of plans for economic and social development, and the promotion of high-quality development.

During the census, over 10,000 agencies were established in Chongqing at municipal, district, township, and village levels, while more than 200,000 personnel were hired for the assignment.

Census institutions and personnel overcame difficulties posed by the epidemic to successfully perform a thorough census of all households and populations in the municipality.

Electronic data collection methods were adopted for the direct reporting of data in real-time, while census subjects were able to report their details independently using a QR code link. In addition, departmental administration was strengthened through electronic applications, including big data and mobile phones, which improved the quality and efficiency of census work.

Xiang Tielin, director of the Leadership Group for the Seventh National Population Census of Chongqing Municipal People’s Government, and deputy director of the Chongqing Municipal Bureau of Statistics attended the conference to deliver the following census results and key findings.
