Centro-Sul
Centro-Sul (Portuguese pronunciation: [ˌsẽtɾuˈsuw], South-Central) is a geographic area that encompasses the Southeastern, Southern and Central-West regions of Brazil (see Brazil Regional Division), excluding the north of Minas Gerais, most of Mato Grosso, and parts of Tocantins.
Demographics
About 135 million Brazilians live in this region. Most industries are concentrated in the area and are responsible for ~75% of the national GDP. In addition, the majority of the population is predominantly of European descent, and more than half of the population self-identifies as White Brazilian.
The region also is characterized by having a high standard of living (HDI of ~0.787, in average), compared to the rest of the country.
Although it was always the richest geoeconomic region, until the 1980s it was much poorer than neighboring Uruguay and Argentina.
Due to strong industrialization, the development of the South and Center-West regions occurred less recently with the expansion of agribusiness.
The Centro Sul region now has similar development to that of Uruguay and Argentina; the richest South American countries.
