People Brazil
Population: 176,029,560 note: Brazil took an intercensal count in August 1996 which reported a population of 157,079,573; that figure was about 5% lower than projections by the US Census Bureau, which is close to the implied underenumeration of 4.6% for the 1991 census; estimates for this country explicitly take into account the effects of excess mortality due to AIDS; this can result in lower life expectancy, higher infant mortality and death rates, lower population and growth rates, and changes in the distribution of population by age and sex than would otherwise be expected (July 2002 est.)
Age structure: 28% (male 25,140,954; female 24,199,276) 15-64 years: (male 3,992,017; female 5,863,234) (2002 est.)
Population growth rate: 0.87% (2002 est.)
Birth rate: 18.08 births/1,000 population (2002 est.)
