Instituto Brasileiro de Geografia e Estatística

Description

It is a compilation, in digital format, of the smallest territorial portion used by IBGE to plan and carry out data collection for the Census and Statistical Surveys: the Enumeration Area. This corresponds to a section of the national territory, considering the Political-Administrative Division and other territorial structures, which allows the collection of statistical information within the due collection period.

It depicts the stage of IBGE's cadastral systems in time, according to the processes of data acquisition, treatment, management and updating, to be used in the construction of the Census Mapping for the Population Censuses and Household Surveys. It constitutes an overview of the Brazilian Political-Administrative Division in force on the reference date, including States, Federal District, Municipalities, Districts and Subdistricts, whose cadastral identification comprises the code of the enumeration area. In addition, each enumeration area brings information capable of organizing the collection, such as its urban or rural location/feature and status of locations, such as cities, villages, urban centers and rural agglomerations.

As of 2020, it became possible to distinguish the Mesh of Enumeration Area or, simply Census Mesh, from the new product, the Intermediate Mesh of Enumeration Area. The former is linked to the disclosure of the results of operations such as Population Censuses, Censuses of Agriculture and Population Count. In this case, as it is the result of a thorough survey of the Brazilian territory, it will have a much larger set of information than the Intermediate Mesh of Enumeration Areas. This, in turn, will bring annually updated information on territorial changes that affect the form and classification of enumeration areas on a annual basis, although it does not bring the statistical information brought by the former.
