Regions of Brazil

From Wikipedia, the free encyclopedia
(Redirected from Brazil Regional Division)

Brazil is geopolitically divided into five regions (also called macroregions), by the Brazilian Institute of Geography and Statistics, which are formed by the federative units of Brazil. Although officially recognized, the division is merely academic, considering geographic, social and economic factors, among others, and has no political effects other than orientating Federal-level government programs.[1] Under the state level, they are further divided into intermediate regions and even further into immediate regions.[2]

Central-West Region

[edit]
Main article: Central-West Region, Brazil
  • Area: 1,612,007.2 km2 (18.86%)
  • Population: 16,289,538 (7.2 people/km2; 6.4%)
  • GDP: R$279 billion / US$174,3 billion (2008; 8.3%) (4th)
  • Climate: Savanna climate (hot, with little precipitation during winter in the northeast and the east; Tropical in the east and in the west; Equatorial in the north; Some temperate climate places in the south).
  • States: Goiás, Mato Grosso, Mato Grosso do Sul, Distrito Federal (Federal District).
  • Largest Cities: Brasília (national capital) (2,562,963); Goiânia (1,318,148); Campo Grande (796,252); Cuiabá (556,298); Aparecida de Goiânia (442,978); Anápolis (334,613).
  • Economy: Livestock,[3] Soybeans, Maize, Sugarcane, Cotton, Tomato,[4][5] Nickel, Copper, Gold,[6] tourism.[7][8][9]
  • Transport: Highways where they are present (mostly in the center and east regions); transport by rivers is common in the north and in the east; airplanes are used in remote and smaller communities.
  • Vegetation: Mainly savanna-like vegetation, including the Pantanal (Chaco, in Paraguay), flooded areas in the west, equatorial rainforests in the north.
  • Notable characteristics: With a low population density, most of the land in the region is used for grazing instead of agriculture. The region is also the least industrialized in the country, based mainly in food & meat processing.

Southeast Region

[edit]
Main article: Southeast Region, Brazil

South Region

[edit]
Main article: South Region, Brazil
  • Area: 577,214 km2 (6.75%)
  • Population: 29.937.706 (43.46 people/km2, 12.5%)
  • GDP: R$503 billion / US$313,8 billion (2008; ~15%) (2nd)
  • Climate: Subtropical by the coast, hot to moderately hot in the summer, mild and very humid winters and temperate by the mountain range, the valleys and the plateaus in the interior, with moderate temperatures in the summer and cold in the winter, with well distributed rainfalls. Snow is relatively common, mainly in the highlands (for example in Santa Catarina state's São Joaquim).
  • States: Paraná, Rio Grande do Sul, Santa Catarina
  • Largest Cities:[14] Curitiba (1,764,540); Porto Alegre (1,413,094); Joinville (520,905); Londrina (511,278); Caxias do Sul (441,332); Florianópolis (427,298); Maringá (362,329); Pelotas (328,864); Canoas (325,188); Ponta Grossa (314,527); Blumenau (312,634); Cascavel (289,339); Foz do Iguaçu (255,900); and Santa Maria (262,368).
  • Economy: Machinery and automobile industries, textiles, shoes, information technology[8]tourism,[7] soy, maize, wheat, tobacco, rice, apple,[5][4] wine,[15]livestock,[3] coal,[16][17][6] energy production.[9][18]
  • Transport: There are many developed highways and railways throughout the region, although the latter is mainly used for freight. Rivers are used when possible.
  • Vegetation: Rainforests along the coast (Mata Atlântica), subtropical semiciduous in the north and west (Araucárias) and prairie-like vegetation in the south (Pampas). Little native vegetation still remains due to deforestation.
  • Notable characteristics: The South Region of Brazil is historically characterized by its high standard of living, with considerably better social indicators, which include some of the cities with the highest HDI levels in the country, including their capitals. Cities also feature an advanced level of urbanism in comparison with other parts of Brazil. The region is almost the newest in terms of urbanization, it was recently populated by European immigrants (almost 19th century immigration and refugees of World War I and World War IIs). They have added to the local culture, especially in architecture, cuisine and forms of agriculture. Southern region, however, is not immune from poverty, violence and other social issues, especially in the larger cities, even though in a lower level than poorer areas in the country. The state of Santa Catarina is proportionally the Whitest state in Brazil with over 87% of its population being European. The other southern states also have the highest percentage rates of European population.

Ethnic composition of regions

[edit]

The composition of regions of Brazil according to autosomal genetic studies focused on the Brazilian population (which has been found to be a complex melting pot of European, African and Native Americans components):

A 2011 autosomal DNA study, with nearly 1000 samples from all over the country ("whites", "pardos" and "blacks"), found a major European contribution, followed by a high African contribution and an important Native American component.[29] The study showed that Brazilians from different regions are more homogeneous than previously thought by some based on the census alone. "Brazilian homogeneity is, therefore, a lot greater between Brazilian regions than within Brazilian regions."[30]

Region[29] European African Native American
Southeast Brazil 74.20% 17.30% 7.30%
Southern Brazil 79.50% 10.30% 9.40%
Northeast Brazil 60.10% 29.30% 8.90%
Northern Brazil 68.80% 10.50% 18.50%

According to an autosomal DNA study from 2010, a new portrayal of each ethnicity contribution to the DNA of Brazilians, obtained with samples from the five regions of the country, has indicated that, on average, European ancestors are responsible for nearly 80% of the genetic heritage of the population. The variation between the regions is small, with the possible exception of the South, where the European contribution reaches nearly 90%. The results, published by the scientific American Journal of Human Biology by a team of the Catholic University of Brasília, show that, in Brazil, physical indicators such as colour of skin, eyes and hair have little to do with the genetic ancestry of each person, which has been shown in previous studies (regardless of census classification).[31] Ancestry informative SNPs can be useful to estimate individual and population biogeographical ancestry. Brazilian population is characterized by a genetic background of three parental populations (European, African, and Brazilian Native Amerindians) with a wide degree and diverse patterns of admixture. In this work we analyzed the information content of 28 ancestry-informative SNPs into multiplexed panels using three parental population sources (African, Amerindian, and European) to infer the genetic admixture in an urban sample of the five Brazilian geopolitical regions. The SNPs assigned apart the parental populations from each other and thus can be applied for ancestry estimation in a three hybrid admixed population. Data was used to infer genetic ancestry in Brazilians with an admixture model. Pairwise estimates of F(st) among the five Brazilian geopolitical regions suggested little genetic differentiation only between the South and the remaining regions. Estimates of ancestry results are consistent with the heterogeneous genetic profile of Brazilian population, with a major contribution of European ancestry (0.771) followed by African (0.143) and Amerindian contributions (0.085). The described multiplexed SNP panels can be useful tool for bioanthropological studies but it can be mainly valuable to control for spurious results in genetic association studies in admixed populations."[32]

Region[32] European African Native American
Central-West Brazil 65.90% 18.70% 11.80%
Southeast Brazil 79.90% 14.10% 6.10%
South Brazil 87.70% 7.70% 5.20%
Northeast Brazil 77.40% 13.60% 8.90%
North Brazil 71.10% 18.20% 10.70%

An autosomal DNA study from 2009 found a similar profile "all the Brazilian samples (regions) lie more closely to the European group than to the African populations or to the Mestizos from Mexico."[33]

Region[33] European African Native American
Central-West Brazil 66.3% 21.7% 12.0%
Southeast Brazil 60.7% 32.0% 7.3%
South Brazil 81.5% 9.3% 9.2%
Northeast Brazil 66.7% 23.3% 10.0%
North Brazil 60.6% 21.3% 18.1%

According to another autosomal DNA study from 2008, by the University of Brasília (UnB), European ancestry dominates in the whole of Brazil (in all regions), accounting for 65.90% of heritage of the population, followed by the African contribution (24.80%) and the Native American (9.3%); the European ancestry being the dominant ancestry in all regions including the Northeast of Brazil.[34]

A study from 1965, "Methods of Analysis of a Hybrid Population" (Human Biology, vol 37, number 1), led by geneticists D. F. Roberts and R. W. Hiorns, found out the average Northeastern Brazilian to be predominantly European in ancestry (65%), with minor but important African and Native American contributions (25% and 9%).[35]
