Update of Municipal Maps

Description

The "Update of Municipal Maps" (1) refers to Municipal Maps of the Municipalities that have had their borders updated somehow. These updates have not reached all the Brazilian municipalities, so that maps have not been produced for all of them.

Municipal Maps represent the intramunicipal Political Administrative Division (districts and subdistricts), intermunicipal and interstate borders and the main planimetric elements and hydrography elements.

The Municipal Maps annually produced by the IBGE consider the updated status of the Brazilian Political and Administrative Division (DPA). The dynamics of DPA reflects the updates in the municipal borders of the municipalities, within the Technical Cooperation Agreements (ACT) between the IBGE and state bodies in charge of the Political Administrative Division.

The territory updates occur as a result of one of the following factors: publication of a new law, legal decision and technical reports issued by the respective state bodies in charge of the political-administrative division of each state and sent to the IBGE. However, we explain the most common factors are cartographic adjustments following technical reports produced by the States and the publication by the State of a new law that updates municipal borders.

The versions of 2012 to 2019 update the collection of the 2010 Census Municipal Statistical Maps:

Note(1): The publication "Update of Municipal Maps" went into effect as a new version of "Municipal Maps of Population Estimates"

About the publication - 2021

The annual population estimates produced by the IBGE take into account the current situation of the Brazilian Political-Administrative Division (DPA), including the updating in the municipal borders based on analyses in the scope of technical cooperation agreements that the IBGE maintains with state offices aiming at consolidating municipal borders.

The territorial updating sent from those offices to the IBGE in the period between May 1, 2020 and April 30, 2021 were incorporated into the methodology of the 2021 Population Estimates. The list of participating municipalities can be accessed in the following document: Estimativas da população residente para os municípios e para as unidades da federação brasileiros com data de referência em 01 de julho de 2021: [notas metodológicas], available on the IBGE website.

FEDERATION UNIT	NUMBER OF MUNICIPALITIES UPDATED

PI	03
CE	02
AL	06
BA	02
SP	08
PR	15
RS	09

It should be highlighted that the municipalities not included in the list of the 2021 Population Estimates did not have their maps updated that year, and their maps can be found in the repository of the 2010 Census or in the folders of subsequent years, between 2011 and 2020, if they had their borders updated.
