Amazônia Legal (Portuguese pronunciation: [amaˈzonjɐ leˈɡaw]) also known as Brazil's Legal Amazon or BLA is the largest socio-geographic division in Brazil, containing all nine states in the Amazon basin. The region was created in 1948 based on studies of the Brazilian government on how to plan the economic and social development of the Amazon region.
It is an official designation that encompasses all seven states of the North Region (Acre, Amapá, Amazonas, Pará, Rondônia, Roraima and Tocantins), as well as part of Mato Grosso in the Center-West Region and most of Maranhão in the Northeast Region. Amazônia Legal is a 5,016,136.3 km2 region with around 24 million inhabitants, in other words 59% of Brazil is part of Amazônia Legal but only 12.34% of the Brazilian population lives there. The administrative unit was initially established by Federal Law No. 5.173 (Art. 2).
Although called Amazônia Legal the region overlaps three different biomes: all of Brazil's Amazon biome, 37% of the Cerrado biome and 40% of the Pantanal biome. The main characteristic of the region is the abundant and tropical vegetation, including large sections of rainforest.
