Description
The registry of Brazilian municipalities located in Metropolitan Areas – RMs, Urban Agglomerations and Integrated Development Areas – RIDEs is quarterly updated by the Surveys of Metropolitan Areas, Urban Agglomerations and Integrated Development Areas. The main goal is to identify the political-administrative units in Brazil located in Metropolitan Areas, Urban Agglomerations and Integrated Development Areas, which deserve specific treatment on behalf of their planning and management peculiarities.
Metropolitan Areas and Urban Agglomerations consist of arrangements of bordering municipalities and are established by a complementary state law, pursuant to Article 25, paragraph 3 of the 1988 Federal Constitution, aiming at integrating the organization, planning and execution of the public assignments of general interest. In the list provided by the IBGE, there are also categories associated to the divisions: metropolitan belts, metropolitan arches (highways), metropolitan expansion areas, metropolitan subdivisions, and others. The Integrated Development Areas, in turn, are defined as administrative areas that include different Federation Units. These divisions are created by specific legislation, in which the Federation Units that compose it are listed and the operational structure and the interests of the political-administrative member-units are defined. In the case of RIDEs, the jurisdiction to create it belongs to the Federal Government, pursuant to Article 21, subsection 9; Articles 43 and 48, subsection 4, of Federal Constitution.

About the publication - 2021
The current revision of the IBGE shows the creation of new Metropolitan Areas (RMs) in the states of Santa
Catarina and São Paulo.
According to Complementary Law no. 788/2021, the RMs of
Joinville, North Plateau and Jaraguá do Sul were created in Santa Catarina. In the State of São Paulo, Complementary Law no.
1,359/2021 created the RM of São José do Rio Preto, Complementary Law no. 1,360/2021 established the RM
of Piracicaba, whereas Complementary Law no. 1,362/2021 created the RM of Jundiaí. The major
consequence of the creation of the RMs of Piracicaba and Jundiaí was the extinction of the AGLOs of
Piracicaba and Jundiaí.
Neither the Development Integrated Regions (RIDEs) nor the other
Metropolitan Areas of the Brazilian states changed. Currently, Brazil has 81 Metropolitan
Areas. The state with the highest number of RMs is Santa Catarina (14), followed by
Paraíba (12), Alagoas (9) and São Paulo (9). There are three Urban Agglomerations, being one in the State
of São Paulo and two in Rio Grande do Sul.
According to the Federal Constitution of 1988, Metropolitan Areas and Urban Agglomerations are divisions established by state
complementary laws, aiming at the
organization, planning and implementation of public services of common interest. As stated under
Article 25, 3rd paragraph of the Federal Constitution, States are responsible for establishing
Metropolitan Areas and Urban Agglomerations.
On their turn, RIDEs are established as administrative
areas that comprise different Federation Units. RIDEs are created through a specific
legislation, listing the municipalities involved and establishing their
operation and the interests of the participating political-administrative units. According to Article 43, 1st paragraph of the
Federal Constitution, the Federal Government is responsible for creating
RIDEs.
Another highlight is the change in the geocodification of the Metropolitan Areas, Integrated
Development Regions and Urban Agglomerations. The new codification developed by the IBGE
aimed at fitting the new legal premises for the creation of Metropolitan Areas (RMs)
in Brazil, available in the Statute of Major Cities (Law no. 13,089, of January 12, 2015). A
detailed explanation about the new geocodification rules for these territorial divisions
can be found in Metropolitan Areas, Integrated Development Regions and
Urban Agglomerations - Technical Note 01/2022.

FAQ
Is the IBGE responsible for the Metropolitan Areas, Urban Agglomerations and Integrated Development Areas delimitation?
No. The Metropolitan Areas and Urban Agglomerations consist of arrangements of bordering municipalities and are established by a complementary state law, in accordance with Article 25, paragraph 3 of the 1988 Federal Constitution, aiming to integrate the organization, planning and execution of public functions of general interest. In the list provided by the IBGE, there are also categories associated to these subdivisions: metropolitan belts, metropolitan arches (highways), metropolitan expansion areas, metropolitan subdivisions, and others. The Integrated Development Areas, in turn, are defined as administrative areas that include different Federation Units. These subdivisions are created by specific legislation, under which the Federation Units forming them are listed, and which definesthe operational structure and the interests of the political-administrative member-units. In the case of RIDEs, the jurisdiction to create them belongs to the Federal Government, in accordance with Article 21, subsection 9; Articles 43 and 48, subsection 4, of the Federal Constitution.

The main goal is to identify the political-administrative units in Brazil located in Metropolitan Areas, Urban Agglomerations and Integrated Development Areas, which demand a specific approach on behalf of their planning and management peculiarities. Besides that, the identification of the municipalities that form those subdivisions is essential for the definition of subdivisions in the sample surveys.
What is the difference between Metropolitan Areas and Integrated Development Areas – RIDEs?
Metropolitan Areas consist of arrangements of bordering municipalities and are established by complementary state law, that is, they can only be formed by municipalities from the same State. RIDEs are defined as administrative areas that include municipalities from different States and, consequently, are created by specific legislation by the National Congress.
Which is the frequency of the Metropolitan Areas, Urban Agglomerations and Integrated Development Areas updating?
