Roraima (Pemon: roro imã, "Parrot + Mount(s)" i.e. "Green Peak", Portuguese pronunciation: [ʁoˈɾajmɐ][2]) is the northernmost and least populated state of Brazil, located in the Amazon region. It borders the states of Amazonas and Pará, as well as the nations of Venezuela and Guyana. The population is approximately 450,000 (2010) and the capital is Boa Vista. Roraima is the Brazilian state with the fewest municipalities, 15 in total.


Tepequém, in Roraima.

The climate of Roraima is tropical with an annual mean temperature of 26°C (78.8°F). The state's southern part is located in the Amazon rainforest, while the north has open grassland fields, and there is a small strip of savanna to the east. The state is rich in mineral deposits - especially gold, diamonds, cassiterite, bauxite, marble and copper. Many of these deposits are located in indigenous reserves, and illegal mining has resulted in frequent conflicts with the native population, especially the Yanomami and the Macuxi and allied groups.

The Monte Roraima National Park is located around one of the highest mountains of both Venezuela (outside of the Andes) and Brazil, and the highest in Guyana, a 2,875 m (9,432 ft) high tepui known as Monte Roraima. Only a small fraction of the mountain is in Brazilian territory, however, and the highest point of the Brazilian part is at 2,734 metres (8,970 ft).[3]


Except for the higher mountains where the climate is cooler but very wet, Roraima has an equatorial climate. This is a type of tropical climate in which there is no dry season – all months have mean precipitation values of at least 60 mm. It is usually found at latitudes within five degrees of the equator – which are dominated by the Intertropical Convergence Zone. The equatorial climate is denoted Af in the Köppen climate classification. Tropical rainforest is the natural vegetation in equatorial regions.


Main article: History of Roraima

Since the beginnings of the 16th century, the region now considered the state of Roraima was disputed territory, because of its rich mineral reserves. It was sought by the Spanish, Portuguese, Dutch and English until the beginning of the last century. But in 1943, together with a section from the state of Amazonas, the Federal Government created the territory of Rio Branco, which became Roraima in 1962. In 1988, Roraima became a state by decision of the National Congress. The name of the state was taken from Mount Roraima, whose name comes from the Pemon words “roroi” (“cyan”) and “ma” (“large”). One of the main archaeological site is the Pedra Pintada, Roraima, with ancient rock art and engravings.


According to the IBGE of 2007, there were 405,000 people residing in the state. The population density was 1.8 inh./km².

Urbanization: 80.3% (2004); Population growth: 4.6% (1991–2000); Houses: 97,465 (2005).[4]

The latest PNAD (National Household Survey) data reveal the following numbers: 278,000 Brown (Multiracial) people (68.8%), 81,000 White people (20.0%), 29,000 Black people (7.4%), 15,000 Asian or Amerindian people (3.8%).[5]

The Brazilian Indian Agency, (FUNAI) estimates the state's indigenous population at 30,715.[6] The largest indigenous groups are the Macuxi (16,500)[7] and the better-known Yanomami (11,700).[8] Much of the state's indigenous population lives in several large, legally recognized indigenous reserves and a number of smaller ones, totalling 46.13% of the land area of the state.[9]

The blue of the flag represents the pure air and the sky of Roraima, the white strip symbolizes peace, and the green to the right represents the forests and fields. The star - symbolizing the state in the national flag of Brazil - is yellow, which symbolizes the mineral resources of the state. The red line in bottom stands for the equator, which cuts through the state. The flag was designed by the artist Mário Barreto, and was adopted by Law No.133 of June 14, 1996.
