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.

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.
