In data collection for the Population Census, the IBGE enumerators will go all over Brazil and visit more than 70 million housing units to search for the answers that will provide information on the population and their living conditions.

Such a huge operation engages a number of persons in different activities. Therefore, the IBGE plans each action carefully and conducts different types of tests prior to data collection to make sure that questionnaires, applications, systems and other actions will work properly. By means of Census tests, it is possible to identify possible necessary improvements and confirm what is operating as expected.
