BEIJING — Vice-Premier Han Zheng has called for solid efforts to carry out a high-quality national population census and ensure full coverage, accuracy, and authenticity.

Han, also a member of the Standing Committee of the Political Bureau of the Communist Party of China Central Committee and head of the State Council leading group on the seventh national population census, made the remarks during an inspection tour in Beijing on Nov 3.

Data on China's population size, structure, and distribution will offer statistical support for the country to improve its population strategy and policy system, formulate economic and social plans and advance high-quality development, Han noted.

Citizens' personal information should be strictly protected, said Han, adding that the entire census should be advanced in accordance with the law.

China conducts a national population census every 10 years. The seventh national population census began on Nov 1 and is slated for completion on Dec 10.
