What was the reason for Brazil's population increase between the years of 1940 and 1970?
Brazil
The population of Brazil, as recorded by the 2008 PNAD, was approximately 190 million (), 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. The first census in Brazil was carried out in 1872 and recorded a population of 9,930,478. From 1880 to 1930, 4 million Europeans arrived. Brazil's population increased significantly between 1940 and 1970, because of 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 and 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. 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.
