Consultation with society is an indispensable step in the preparation of the Population Census and has the objective of guiding census elaboration, so that the operation can translate the demands of society for information and, thus, fulfill its ultimate aim, according to the institutional mission that reads: "To portray Brazil by providing information required to the understanding of its reality and the exercise of citizenship." Therefore, democratic and comprehensive consultation – encompassing governmental bodies, universities and survey institutes, the private sector and other organizations – is of fundamental importance to identify gaps in data production, set priorities and understand how data is used. With that in mind, the IBGE has made available on its website, between March and May 2018, a consultation form for all citizens, by means of which it was possible to record suggestions and commentaries and to detail, considering the answers given, the impact of information and the suitability of such demands to specifications of the census operation.
