| Abstract: | We have accumulated some valuable experience through 2 successful population censuses in 1953 and 1964. A series of special census committees were established at each administrative level--from central government to local areas. Periodic 2-way telephone communication between higher and lower offices was planned. The census was conducted on the basis of permanent population in 1953 and 1964. A standard time of June 30, midnight was used in both cases. Census items must be clear, easy to use, and standardized. Name, relationship to head of household, sex, age, race, and present address were listed in 1954. Birth date, class, educational level, and occupation were added in 1964. For accurate data census districts and their boundaries must be clearly marked. Registering the whole family by head of household at the nearby temporary census station was found to be convenient, efficient, and accurate. Door-to-door visits by census clerks were also used. To complete such a cumbersome task in a short period of time high-quality census personnel were trained to fully understand the significance, the regulations, and the technical details of the task. Nationwide education and propaganda about the census were important for success. 3 levels of reporting (county, province, and central) in 1953 and 4 levels in 1964 were used to check results and correct mistakes. The announcement of the results to the public after the entire census was completed provided an opportunity for the public to confirm the data and correct mistakes. This process of confirmation is an essential quality control step. |
