Brazil has a high level of urbanization with 87.8% of the population residing in urban and metropolitan areas. The criteria used by the IBGE (Brazilian Institute of Geography and Statistics) in determining whether households are urban or rural, however, are based on political divisions, not on the developed environment. Nowadays, the country has 5,570 municipalities. With two exceptions, the state capitals are all the largest cities in their respective states: Florianópolis, the capital of Santa Catarina is its second-largest city after Joinville, while Vitória is only the fourth-largest city in Espírito Santo, although it is located in that state's largest metropolitan area.
