Metropolitan Areas, Urban Agglomerations and Integrated Development Areas
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.

There are three Urban Clusters, one in the state of São Paulo and two in Rio Grande do Sul.
Metropolitan Areas and Urban Clusters are areas established by supplementary state law, in accordance with the provisions of the 1988 Federal Constitution, with the aim of integrating the organization, planning and execution of public functions of common interest. The definition of Metropolitan Areas and Urban Clusters is the responsibility of the states, according to paragraph 3 of Article 25 of the Federal Constitution.
Integrated Development Areas (RIDEs), in turn, are defined as administrative regions that encompass different Federation Units. RIDEs are created by specific legislation, in which the municipalities that comprise them are listed, in addition to defining the operating structure and interests of the participating political-administrative units. In the case of RIDEs, the power to create them lies with the Union, in accordance with paragraph 1 of article 43 of the Federal Constitution.
