Demographics

The population of Brazil as recorded by the 2008 PNAD was approximately 190 million (22.31 inhabitants per square kilometer), with a ratio of men to women. of 0.95:1[193] and 83.75% of the population defined as urban. The population is heavily concentrated in the Southeastern (79.8 million inhabitants) and Northeastern (53.5 million inhabitants) regions, while the two most extensive regions, the Center-West and the North, which together make up 64.12% of the Brazilian territory, have a total of only 29.1 million inhabitants.

Population increased significantly between 1940 and 1970, due to a decline in the mortality rate, even though the birth rate underwent a slight decline. In the 1940s the annual population growth rate was 2.4%, rising to 3.0% in the 1950s and remaining at 2.9% in the 1960s, as life expectancy rose from 44 to 54 years and to 72.6 years in 2007. It has been steadily falling since the 1960s, from 3.04% per year between 1950-1960 to 1.05% in 2008 and is expected to fall to a negative value of –0.29% by 2050 thus completing the demographic transition.

According to the National Research by Household Sample (PNAD) of 2008, 48.43% of the population (about 92 million) described themselves as White; 43.80% (about 83 million) as Brown (Multiracial), 6.84% (about 13 million) as Black; 0.58% (about 1.1 million) as Yellow; and 0.28% (about 536 thousand) as Amerindian, while 0.07% (about 130 thousand) did not declare their race.

In 2007, the National Indian Foundation reported the existence of 67 different uncontacted tribes, up from 40 in 2005. Brazil is believed to have the largest number of uncontacted peoples in the world.

Most Brazilians descend from the country's indigenous peoples, Portuguese settlers, and African slaves. ince the arrival of the Portuguese in 1500 miscegenation between these three groups has takenplace. The brown population (as multiracial Brazilians are officially called) is a broad category that includes Caboclos (descendants of Whites and Indians), Mulattoes (descendants of Whites and Blacks) and Cafuzos (descendants of Blacks and Indians). Caboclos form the majority of the population in the Northern, Northeastern and Central-Western regions. A large Mulatto population can be found in the eastern coast of the northeastern region from Bahia to Paraíba and also in northern Maranhão, southern Minas Gerais and in eastern Rio de Janeiro. From the 19th century, Brazil opened its borders to immigration. About five million people from over 60 countries migrated to Brazil between 1808 and 1972, most of them from Portugal, Italy, Spain, Germany, Japan and the Middle-East.

In 2008, the illiteracy rate was 11.48% and among the youth (ages 15–19) 1.74%. It was highest (20.30%) in the Northeast, which had a large proportion of rural poor. Illiteracy was high (24.18%) among the rural population and lower (9.05%) among the urban population. In 2006 nearly 50,000 people were murdered in Brazil. More than 500,000 people have been killed by firearms in Brazil between 1979 and 2003, according to the UN report.

Catholicism is dominant, making Brazil the largest Catholic nation in the world. According to the 2000 Demographic Census (the PNAD survey does not inquire about religion), 73.57% of the population followed Roman Catholicism; 15.41% Protestantism; 1.33% Kardecist spiritism; 1.22% other Christian denominations; 0.31% Afro-Brazilian religions; 0.13% Buddhism; 0.05% Judaism; 0.02% Islam; 0.01% Amerindian religions; 0.59% other religions, undeclared or undetermined; while 7.35% have no religion.

The largest metropolitan areas in Brazil are São Paulo, Rio de Janeiro, and Belo Horizonte — all in the Southeastern Region — with 19.5, 11.5, and 5.1 million inhabitants respectively.[220] Almost all of the state capitals are the largest cities in their states, except for Vitória, the capital of Espírito Santo, and Florianópolis, the capital of Santa Catarina. There are also non-capital metropolitan areas in the states of São Paulo (Campinas, Santos and the Paraíba Valley), Minas Gerais (Steel Valley), Rio Grande do Sul (Sinos Valley), and Santa Catarina (Itajaí Valley).
