Intermediate and Immediate Geographic Regions in the context of "Municipalities of Brazil"

Brazil is geopolitically divided into five regions (also called macroregions), by the Brazilian Institute of Geography and Statistics, which are formed by the federative units of Brazil. Although officially recognized, the division is merely academic, considering geographic, social and economic factors, among others, and has no political effects other than orientating Federal-level government programs. Under the state level, they are further divided into intermediate regions and even further into immediate regions.

This is a list of the municipalities in the state of São Paulo (SP), located in the Southeast Region of Brazil.

São Paulo is divided into 645 municipalities, which, since 2017, have been grouped into 11 intermediate and 53 immediate regions.

A microregion (Portuguese: Microrregião) was a legally defined area in Brazil consisting of a group of municipalities. They were abolished in 2017 and replaced by Intermediate and Immediate Geographic Regions. Microregions were grouped together into mesoregions. In theory, Brazilian law provided for member municipalities to cooperate on matters of common interest, but in practice, the divisions were used primarily for statistical purposes by the Brazilian Institute of Geography and Statistics.

A mesoregion (Portuguese: Mesorregião) was a subdivision of the Brazilian states, grouping together various municipalities in proximity and with common characteristics. They were abolished in 2017 and replaced by intermediate and immediate geographic regions. The mesoregions were created by the Brazilian Institute of Geography and Statistics for statistical purposes and did not, therefore, constitute political or administrative areas. They were further divided into microregions.
