North Region

The North Region of Brazil is the largest Region of Brazil, corresponding to 45.27% of the national territory. It is the least inhabited of the country, and contributes with a minor percentage in the national GDP and population. It comprises the states of Acre, Amapá, Amazonas, Pará, Rondônia, Roraima and Tocantins.

Its demographic density is the lowest in Brazil considering all the regions of the country, with only 3.8 inhabitants per km2. Most of the population is centered in urban areas.

Belém International Airport and Manaus International Airport connect the North Region with many Brazilian cities and also operate some international flights.

The North is home to the Federal University of Amazonas and Federal University of Pará.

Geography

The Amazon represents over half of the planet's remaining rainforests and comprises the largest and most species-rich tract of tropical rainforest in the world. Wet tropical forests are the most species-rich biome, and tropical forests in the Americas are consistently more species rich than the wet forests in Africa and Asia. As the largest tract of tropical rainforest in the Americas, the Amazonian rainforests have unparalleled biodiversity. More than 1/3 of all species in the world live in the Amazon Rainforest.

The region is home to about 2.5 million insect species, tens of thousands of plants, and some 2000 birds and mammals species. To date, at least 40,000 plant species, 3,000 fish, 1,294 birds, 427 mammals, 428 amphibians, and 378 reptiles have been scientifically classified in the region. Scientists have described between 96,660 and 128,843 invertebrate species in Brazil alone.

The diversity of plant species is the highest on earth with some experts estimating that one square kilometre may contain over 75,000 types of trees and 150,000 species of higher plants. One square kilometre of Amazon rainforest can contain about 90,790 tonnes of living plants. This constitutes the largest collection of living plants and animal species in the world. One in five of all the birds in the world live in the rainforests of the Amazon. To date, an estimated 438,000 species of plants of economic and social interest have been registered in the region with many more remaining to be discovered or catalogued.

Ethnic groups

The population of northern Brazil is largely made up of Caboclos, descendants of Indians and Europeans - mostly Portuguese, French and Spanish. North of Brazil has received and continues to receive large migration of people from South and Southeast of the country. In the 20th century, the North also received great migration from the Northeast, who were working in the rubber plantations of Amazonas and Acre.
