According to IBGE (Brazilian Institute of Geography and Statistics) urban areas already concentrate 84.35% of the population, while the Southeast region remains the most populated one, with over 80 million inhabitants.[1] The largest metropolitan areas in Brazil are São Paulo, Rio de Janeiro, and Belo Horizonte — all in the Southeastern Region — with 21, 12, and 5 million inhabitants respectively.[2] In general, state capitals are the largest cities in their states, except for Vitória, the capital of Espírito Santo, and Florianópolis, the capital of Santa Catarina. There are also non-capital metropolitan areas in the states of São Paulo (Campinas, Santos and the Paraíba Valley), Minas Gerais (Steel Valley), Rio Grande do Sul (Sinos Valley) and Santa Catarina (Itajaí Valley).[3]
