“…Even though the Metropolitan Statute establishes a characterization for MRs, presenting minimum criteria for their constitution, specialists argue these requirements could be even more restrictive (Moura and Hoshino, 2015), because according to studies carried out by using IBGE criteria, out of population cuts of medium and large urban concentrations, 26 large urban concentrations with over 750,000 inhabitants were identified, while only 12 are legitimized as metropolises, different from the 74 existing MRs today (Moraes, Guarda and Zacchi, 2018). It is pertinent to point out that IBGE legitimizes the existence of 15 metropolises in Brazil, by updating the Regic (Regions of Influence of Cities) in 2020, namely: Manaus, Belém, Fortaleza, Recife, Salvador, Brasília, Goiânia, Belo Horizonte, Vitória, Rio de Janeiro, São Paulo, Campinas, Curitiba, Florianópolis and Porto Alegre.…”
