Yesterday, February 28, the IBGE completed the household data collection phase of the Population Census, having reached 189,261,144 enumerated persons: 91%, taking as a basis the population estimate released on December 28, 2022. The Institute informs that the Data Processing Phase starts today, March 1st. The dissemination of the first results will take place by the end of April.

The Data Processing Phase encompasses the activities of Census Data Analysis to be carried out by the Census Closing Committee (CFC). We would like to highlight that these tasks - including specific verification of enumeration areas and municipalities selected by the CFC - implies returning to the field in specific cases in order to:

Provide specific supervision, to be carried out by the special supervision team, indicated by the Census Planning and Organization Commission; work on Data Editing and Consistency; work on data imputation; analyze first results; until the First Results are disclosed.

Due to all this caution checking, verifying and refining the collection, in this Data Processing Phase we should highlight that some households will still be visited by enumerators or supervisors. It is also worth saying that the Post-Enumeration Survey is still going on.

As one of the stages of the Population Census, the PPE comprises a sample of nearly 1.5% of the enumeration areas. Its mains goal is to provide resources to assess the coverage and quality of collection.

Possible flaws in information coverage and quality declared by residents are common phenomena in population censuses of several countries, since censuses are complex operations, subject to imprecisions that must be verified and corrected.

The PPE helps verify if there are imprecisions and where they can be found. It directly contributes to the greater transparency of the results of the Population Census, providing elements for society to better interpret and use data. The PPE is also important for identifying areas demanding more attention for future operations and for providing subsidies to the elaboration of population estimates and projections.

The Post-Enumeration Survey is an integral part of the Population Census project. Its basic principles are independence and equality of conditions in relation to the Census. To guarantee these principles, the PPE uses the same concepts and foundations adopted in the Census, as well as the same collection and supervision instruments.


The IBGE has carried out surveys of this nature since the Population Census of 1970. Therefore, direct assessment of Censuses through post-enumeration surveys has been a practice in the country over the last 50 years.
