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.
