Italian Brazilians (Italian: italo-brasiliani, Portuguese: Ãtalo-brasileiros) are Brazilians of full or partial Italian descent, whose ancestors were Italians who emigrated to Brazil during the Italian diaspora, or more recent Italian-born people who've settled in Brazil. Italian Brazilians are the largest number of people with full or partial Italian ancestry outside Italy, with São Paulo being the most populous city with Italian ancestry in the world. Nowadays, it is possible to find millions of descendants of Italians, from the southeastern state of Minas Gerais to the southernmost state of Rio Grande do Sul, with the majority living in São Paulo state. Small southern Brazilian towns, such as Nova Veneza, have as much as 95% of their population of Italian descent.
There are no official numbers of how many Brazilians have Italian ancestry, as the national census conducted by IBGE does not ask the ancestry of the Brazilian people. In 1940, the last census to ask ancestry, 1,260,931 Brazilians were said to be the child of an Italian father, and 1,069,862 said to be the child of an Italian mother. Italians were 285,000 and naturalized Brazilians 40,000. Therefore, Italians and their children were, at most, just over 3.8% of Brazil's population in 1940.
