About Rio de Janeiro
Rio de Janeiro (Brazilian Portuguese pronunciation: [ˈʁi.u d(ʒi) ʒɐˈne(j)ɾu] ), officially the State of Rio de Janeiro (Portuguese: Estado do Rio de Janeiro), is one of the 27 federative units of Brazil. It has the second largest economy of Brazil, with the largest being that of the state of São Paulo. The state, which has 8.2% of the Brazilian population, is responsible for 9.2% of the Brazilian GDP.
The state of Rio de Janeiro is located within the Brazilian geopolitical region classified as the Southeast (assigned by IBGE). Rio de Janeiro shares borders with all the other states in the same Southeast macroregion: Minas Gerais (N and NW), Espírito Santo (NE) and São Paulo (SW). It is bounded on the east and south by the South Atlantic Ocean. Rio de Janeiro has an area of 43,653 km2 (16,855 sq mi). Its capital and most populous city is the city of Rio de Janeiro, which was the capital of the Portuguese Colony of Brazil from 1763 to 1815, of the following United Kingdom of Portugal, Brazil and the Algarves from 1815 to 1822, and of later independent Brazil as a kingdom and republic from 1822 to 1960.
The state is divided into 92 municipalities. The state's 22 largest cities are Rio de Janeiro, São Gonçalo, Duque de Caxias, Nova Iguaçu, Niterói, Campos dos Goytacazes, Belford Roxo, São João de Meriti, Petrópolis, Volta Redonda, Magé, Macaé, Itaboraí, Cabo Frio, Armação dos Búzios, Angra dos Reis, Nova Friburgo, Barra Mansa, Barra do Piraí, Teresópolis, Mesquita and Nilópolis.
Rio de Janeiro is the smallest state by area in the Southeast macroregion and one of the smallest in Brazil. It is, however, the third most populous Brazilian state, with a population of over 16 million people at the 2022 Census (making it the most densely populated state in Brazil), and it has the third longest coastline in the country (after those of the states of Bahia and Maranhão).
In the Brazilian flag, the state is represented by Mimosa, the beta star in the Southern Cross (β Cru).

Rio de Janeiro in Depth
History
European presence in Rio de Janeiro dates back to 1502. Rio de Janeiro originated from parts of the captainships of de Tomé and São Vicente. Between 1555 and 1567, the territory was occupied by the French, who intended to install a colony, France Antarctique. Aiming to prevent the occupation of the Frenchmen, in March 1565, the city of Rio de Janeiro was established by Estácio de Sá.
In the 17th century, cattle raising and sugar cane cultivation stimulated the city's progress, which was definitively assured when the port started to export gold extracted from Minas Gerais in the 18th century. In 1763, Rio de Janeiro became the capital of Colonial Brazil.
Geography
The state is part of the Mata Atlântica biome and is made up of two distinct morphological areas: a coastal plain, known as baixada, and a plateau, which are disposed in parallel fashion from the shoreline on the Atlantic Ocean inland towards Minas Gerais.
The coastline extends 635 kilometers and is formed by the bays of Guanabara, Sepetiba, and Ilha Grande.
There are prominent slopes near the ocean, featuring also diverse environments, such as restinga vegetation, bays, lagoons and tropical forests.
Most of the state however consists of highlands, often higher than 1000 m, formed by several mountain chains like the Serra do Mar which separates Rio from the state of São Paulo.
Economy
Much of the economy of the state of Rio de Janeiro is based on the provision of services, with a significant share of industry and little influence on the agricultural sector, which represents only 0.4% of the product gross domestic state.
In the past, sugar cane and later, coffee had a considerable impact on the economy of Rio de Janeiro. The area around Campos dos Goytacazes was most affected by the fall of sugar cane: at the beginning of the 20th century, Campos had 27 mills in operation and, throughout the century, it was one of the largest producers in the world. In Brazil, however, as of 2020, only two sugar mills were operating in the city.
Demographics
According to the IBGE of 2022, there were 16,055,174 people residing in the state. The population density was 36,697 inhabitants per square kilometre (95,040/sq mi).The last PNAD (National Household Survey) census revealed the following numbers: 6,739,901 White people (42.0%), 6,682,740 Pardo (Multiracial) people (41.6%), 2,594,253 Black people (16.2%), 21,837 Asian people (0.1%), 15,904 Amerindian people (0.1%).
People of Portuguese ancestry predominate in most of the state. The Brazilian census of 1920 showed that 39,74% of the Portuguese who lived in Brazil lived in Rio de Janeiro. Including all of the Rio de Janeiro, the proportion raised to 46,30% of the Portuguese who lived in Brazil.

Visiting Rio de Janeiro
Rio de Janeiro is a state in the Southeast of Brazil. It is a small coastal state wedged between São Paulo to the west, Espírito Santo to the northeast, and Minas Gerais to the north. Rio de Janeiro is most famous for the sun, sand, and samba of its eponymous capital, but the state hosts a wide range of other environments, with quaint colonial villages, rugged mountain parks, lazy coastal towns, and hip beach resort destinations.
