Campos dos Goytacazes (Portuguese pronunciation: [ˈkɐ̃puʒ duʒ ɡojtaˈkaziʃ]) is a municipality located in the northern area of Rio de Janeiro State, Brazil, with a population of 472,300 inhabitants. Its area is 4,031.910 km², which makes it the largest municipality in the state and its elevation is 14 m. Its name comes from the geographical characteristic of the region, very flat with fields (campos in Portuguese) and from the Goytacazes Indians, which inhabited the region. Campos, as the city is usually known, is a macro region of the Northern Fluminense, and is a micro region of Campos dos Goytacazes. The city has a tropical climate.
Colonization of the area started in the 16th century, and the village of São Salvador de Campos de Goytacazes was founded on May 29, 1677. On March 28, 1835 the village was promoted to city status.
The city's distance to Rio de Janeiro city, which is the capital of the state, is 286 kilometres (178 mi). BR-101 is the access highway of the city of Campos. Regular air services are operated from its airport Bartolomeu Lysandro. It is the easternmost municipality in Rio de Janeiro.
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.
