Rio de Janeiro population growth
Rio de Janeiro was founded in 1565 by Portuguese settlers. (A French colony which had been founded in the area in 1555 was destroyed by Portuguese troops in 1560).
In its early years, the population of Rio de Janeiro grew slowly. By 1749, almost two centuries after it had been founded, Rio’s population had grown to just 24,000 people.
However increased immigration from Europe in the 18th and 19th century boosted the city’s population dramatically. Rio was so important to Portugal and so secure that when Napoleon invaded Portugal in 1807, the Portuguese royal family moved to Rio and set up their new capital in the city.
By 1821, just before the Brazilian War of Independence, Rio was home to 113,000 people. The city continued to grow rapidly and by 1872 its population had grown to 274,972 people.
The city’s population hit the milestone of 1 million people early in the 20th century. Subsequent growth was so speedy that, by the end of the 20th century, Rio had grown to accommodate 5.8 million people.
Latest estimates from the IBGE show that the population reached 6,498,837 in 2016.
