Brazilian Girl On The Beach

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 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.
Brazil's 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 Asian; 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.
