 Migration from southern and southeastern regions caused the population to increase in 1959 after the construction of highway BR-364, which connects the north with the rest of the country and was paved in 1986.The period in which the population rose more dramatically was the 1970s, as from 1964 many migrants from all over the country were attracted to the region because of the distribution of land to settlers by INCRA (National Institute of Colonization and Agrarian Reform).The region's wealth of wood in the forest sites and a healthy climate attracted many permanent residents, with a relevant participation of decedents from European migrants, who came firstly to the south of the country and were later attracted to this region by government incentives.
