Population of Rio de Janeiro

The municipality of Rio, the city proper, had a population of 6,051,399 in 2004.

The vast metropolitan region, however, was home to a population of 11.2 million (2003).

Although population growth had been rapid during most of the 20th century, it slowed significantly between 1980 and 1990; during this period, the metropolitan region posted the lowest annual population growth rate, only 0.7 percent, since modern census taking began.

That growth has been uneven, with the municipality of Rio posting only a 0.4 percent annual gain, while outlying suburban municipalities have averaged about 1.5 percent annually.

Rio’s ethnic makeup mirrors its history, which has included people of African, European, and Native American origin.

Nearly two-thirds of the population is of African descent, although this group reflects the widespread racial mixing and intermarriage that have characterized Brazilian society.

While racial tolerance and acceptance are often heralded as characteristics of Brazilian society, whites typically enjoy more privileged social and economic positions than people of African or native descent.
