China's experiences in the quality control of its 1982 population census

The author reports on experiences with China's 1982 census, which covered approximately one billion people and 19 census items. It is noted that "the postenumeration sample survey indicates that the quality of the census enumeration is: 0.071% of overcounts and 0.056% of undercounts. The paper presents principles governing quality control in the population census and explains a series of quality control procedures adopted to reduce possible errors originating in census planning, enumeration and data processing."
