Abstract is: Italians (Italian: Italiani, pronounced [itaˈljaːni]) are the citizens and nationals of Italy and the primarily Romance-speaking ethnic group native to the Italian geographical region and its neighboring insular territories. Italians share a common culture, history, ancestry and language. They are the heirs of three of the most important ancient civilizations: the Greek one which fluorished in Magna Graecia (south Italy), the Etruscan one and the Roman one, which assimilated the former two. Legally, Italian nationals are citizens of Italy, regardless of ancestry or nation of residence (in effect, however, Italian nationality is largely based on jus sanguinis) and may be distinguished from ethnic Italians in general or from people of Italian descent without Italian citizenship and ethnic Italians living in territories adjacent to the Italian peninsula without Italian citizenship. The Latin equivalent of the term Italian had been in use for natives of the geographical region since antiquity. The majority of Italian nationals are native speakers of the country's official language, Italian, or a variety thereof, that is regional Italian. However, many of them also speak a regional or minority language native to Italy, the existence of which predates the national language. Although there is disagreement on the total number, according to UNESCO, there are approximately 30 languages native to Italy, although many are often misleadingly referred to as "Italian dialects". Since 2017, in addition to the approximately 55 million Italians in Italy (91% of the Italian national population), Italian-speaking autonomous groups are found in neighboring nations; about a half million are in Switzerland, as well as in France, the entire population of San Marino. In addition, there are also clusters of Italian speakers in the former Yugoslavia, primarily in Istria, located between in modern Croatia and Slovenia (see: Istrian Italians), and Dalmatia, located in present-day Croatia and Montenegro (see: Dalmatian Italians). Due to the wide-ranging diaspora following Italian unification, World War I and World War II, (with over 5 million Italian citizens that live outside of Italy) over 80 million people abroad claim full or partial Italian ancestry. This includes about 60% of Argentina’s population (Italian Argentines), 1/3 of Uruguayans (Italian Uruguayans), 15% of Brazilians (Italian Brazilians, the largest Italian community outside Italy), more than 18 million Italian Americans, and people in other parts of Europe (e.g. Italians in Germany, Italians in France and Italians in the United Kingdom), the American Continent (such as Italian Venezuelans, Italian Canadians, Italian Colombians and Italians in Paraguay, among others), Australasia (Italian Australians and Italian New Zealanders), and to a lesser extent in the Middle East. Italians have influenced and contributed to fields like arts and music, science, technology, fashion, cinema, cuisine, restaurants, sports, jurisprudence, banking and business. Furthermore, Italian people are generally known for their attachment to their locale, expressed in the form of either regionalism or municipalism.
