People of Portuguese ancestry predominate in most of the state. Other European ethnic groups, such as Swiss, Finnish and Germans settled mostly in the mountainous areas (Nova Friburgo, Petrópolis, etc.) and in the capital. Italians and Spaniards are also present in the capital as well as in the surrounding cities.
People of African descent are numerous, particularly in the metropolitan area of the capital city. Those of mixed-race ancestry (tri-racials, mulatos, and some caboclos and cafuzos) make up the majority of the population in many cities. The city of Itaguaí was considered a Japanese colony in the 20th century, but many of the Asian Fluminenses that one day lived there moved overseas (most of them to Japan) as well to other Brazilian states like São Paulo.
