The population of Campos is 471,737, up from the 436,008 in 2000, but down from the 90's, 80's, 70's, 60's and 50's. The city in the 50's was the second largest of the state of Rio de Janeiro. The reasons behind these reductions are the "crash" that the economy of the town, based on oil, suffered in 1954, something similar that happened in Detroit, with the auto industries. According to the 2010 census, whites represent 70.4% of population, brown or mulatos 20% and black of African 7.1%. Other races represent 3.5% of the population.
