According to the IBGE of 2010, there were 2,562,963 residents in the city. The population density was 423.3 inhabitants per square kilometre (1,096 /sq mi). The racial makeup of the city was 1,008,199 White people (49.15%), 918,305 Brown (Multiracial) people (44.77%), 98,462 Black people (4.80%), 7,996 Asian (0.39%) and 7,154 Amerindian people (0.35%).
In the 1960 census there were almost 140,000 residents in the new Federal District. By 1970 this figure had grown to more than 537,000. In 2000 the population of the Brazilian Federal District was over 2,000,000. Planned for only 500,000 inhabitants, Brasília has seen its population grow much more than expected. Several satellite cities have been created over the years to house the extra inhabitants.
From the beginning, the growth of Brasília was greater than original estimates. According to the original plans, Brasília would be a city for government authorities and staff. However, during the construction period, Brazilians from all over the country migrated to Brasília, seeking public and private jobs.
This makes it the largest city (by population) in the world at the close of the 20th century that did not exist at the beginning of the century (a distinction held by Chicago in the 19th century). Brasília has one of the highest growth rates in Brazil, with its population increasing by 2.82% each year, mostly because of internal migration.
Brasília's inhabitants include a foreign population of mostly embassy workers as well as large numbers of Brazilian migrants. Today, the city has important communities of immigrants and refugees. The Human Development Index in the city is at 0.936 in the year 2000, (developed nation level), and the illiteracy rate is around 4.35%.
