Today, IBGE makes available on its website a group of 27 state maps with the spatial distribution of the population and its relationship with structuring geographic elemets, such as the relief, rivers and roads. Population data is presented according to demographic figures for year 2010, and consists of 316,574 territory units used in the collection of the Population census (enumeration areas). Each state map is presented in a 85 x 110 cm size, and formed by a detailed image of the spatial distribution of the Brazilian population in the national territory. The maps also show all the municipalities and their boundaries, and shows the huge diferences in the forms of settlement all over the country. This material is an essential registry and a vital elemento for the discusion of current geography and of the future strategies of appropriation and use of state territories and of the Brazilian state.
The maps used the Continuous cartographic Base of Brazil to the Millionth Scale (BCIM) of 2010, which includes the topics hydrography, infrastructure, transportation, conservation units, toponyms (names of places) .
The municipal grip of 2010 was also used. It presents 2010, the boundaries of Federation Units and localities, elaborated by IBGE at a 1: 250,000 scale (1 cm = 2.5 km), with updates of 2013 for the states of Pará, Santa Catarina, Rio Grande do Sul and Mato Grosso do Sul. The data on hydroelectric plants was produced by the National Electricity Agency (ANEEL) in 2012.
The maps have been elaborated according to the articulation of natural features, of infrastructure and policies, such as topographic and hydrographic sets, roads, railroads, hydroelectric plants, besides municipal boundaries, conservation units and Indian land and toponyms.
Therefore, these maps presente a very trustworthy and complex portrait of Brazil. In their spatial configuration they show history, nature and a political process. That includes both public action on the territory and forms of political-administrative division, through which the settlement geography of our country is continuously redefined.
