Portuguese-speaking countries. Nevertheless, European and Brazilian Portuguese are completely mutually intelligible. The vast majority of Brazilian characteristics are also found in some rural, remote Portuguese registers (or the African and Asian ones, indicating an Old Portuguese feature lost in Europe), while nearly all distinctive European characteristics can be found in any major dialect of Brazil (such as fluminense, specially its carioca sociolect, and florianopolitano), due to a stronger or more recent Portuguese and other European immigration. Migration from Brazil also led to a great number of Portuguese speakers in the Southern Cone (especially Uruguay with portunhol da pampa), Paraguay (see brasiguayos), other regions of South America (especially Bolivia) except Venezuela, Japan (see Brazilians in Japan 400,000 and dekasegi, official numbers do not include second generation Portuguese speakers and naturalized citizens), South Korea, the Philippines (see Brazilians in the Philippines), and Israel (see Aliyah from Latin America in the 2000s). Rest of South America Although Brazil is the only Portuguese-speaking nation in South America, it has the largest population, area and economy on the continent. Thus, the South American trade bloc Mercosul uses Portuguese alongside Spanish as its working languages. A Spanish influenced Portuguese dialect is spoken in the northern Uruguayan border area with Brazil. Given the proximity and trading relations between Portuguese speaking Brazil, and its respective Spanish speaking nations, Portuguese is offered as a foreign (sometimes obligatory) language course at most schools in Uruguay, Argentina, Paraguay, Venezuela and Bolivia, and has become the second (after English) most studied foreign language in these countries. In Venezuela and Guyana, there are communities of Portuguese immigrants (mostly Madeirans) and their descendants who speak Portuguese as their native language. Given the similarities between Spanish and Portuguese, a colloquial mix of both, unofficially called "Portuñol" or "Portunhol", is spoken by large number of people travelling between Brazil and its Spanish-speaking neighbours. People living in the border areas usually like Paraguay and Uruguay mix the two languages in their daily conversation, a phenomenon similar to Spanglish for Latinos living in the United States. North America There are more than 1.5 million Portuguese Americans and about 300,000 Brazilian Americans living in the United States, and Portuguese is spoken by over 730,000 people at home in the country. There are over 500,000 people of Portuguese descent living in Canada; however, most of the community's population now speaks English or French as their primary language. Portuguese is also
