A census is a collection of information about a group of people. Census information is usually collected in order to obtain some relevant data for the population as a whole. Information is ideally collected from every household, although this is not always possible. Census information is collected by specially trained personnel.
The main reason for a census is to get a figure on population growth. In general, a census is taken once every ten years. Some countries and regions go through significant changes in just one decade. Population growth can vary widely and may not be solely due to the birth rate. Social and economic factors also play a role in population numbers.
Census information is a national concern and should involve everyone in the country where it is held. There is usually a specific census date and all information should be gathered by that date. Undertaking a census is a huge task and there are many issues to consider. The first problem is determining what information is needed.
To gather census information, county areas are divided into enumeration districts. Each individual district is assigned a census interviewer. The interviewer is trained to fully understand every aspect of the information needed. During the month preceding the census, the interviewer begins the preliminary enumeration. The interviewer will visit each building in his assigned district and complete the census questionnaires quickly and accurately.
Once the questionnaires are completed, they are taken to a main census office to be checked and coded. The census information is then ready to be fed into computers capable of generating the required statistics. The quality of the statistics provided depends on the quantity of questionnaires that have been completed, as well as the quality of the questionnaires. If the answers were given honestly and without bias, the statistics will reflect this.
Many people are often concerned that census information may be used for other purposes. The information on the questionnaires is completely confidential. In the United States it is protected by the Statistics Act. No one involved in the census is authorized to provide any information. All census personnel are sworn to secrecy and will not disclose any information held under any circumstances.
