The four national languages of Switzerland are German, French, Italian, and Romansh. German, French, and Italian maintain equal status as official languages at the national level within the Federal Administration of the Swiss Confederation, while Romansh is used in dealings with people who speak it. Latin is occasionally used in some formal contexts, particularly to denote the country (Confederatio Helvetica). In 2020, 62.3% of the population of Switzerland were native speakers of German (either Swiss German or Standard German) at home; 22.8% French (mostly Swiss French, but including some Franco-Provençal dialects); 8% Italian (mostly Swiss Italian, but including Lombard); and 0.5% Romansh. The German region (Deutschschweiz) is roughly in the east, north, and centre; the French part (la Romandie) in the west; and the Italian area (Svizzera italiana) in the south. There remains a small Romansh-speaking native population in Grisons in the east. The cantons of Fribourg, Bern, and Valais are officially bilingual; Grisons is officially trilingual. History The main languages of Swiss residents from 1950 to 2015, in percentages, were as follows: In 2012, for the first time, respondents could indicate more than one language, causing the percentages to exceed 100%. National languages and linguistic regions German The German-speaking part of Switzerland (, , , ) constitutes about 65% of Switzerland (North Western Switzerland, Eastern Switzerland, Central Switzerland, most of the Swiss Plateau and the greater part of the Swiss Alps). In seventeen of the Swiss cantons, German is the only official language (Aargau, Appenzell Ausserrhoden, Appenzell Innerrhoden, Basel-Stadt, Basel-Landschaft, Glarus, Luzern, Nidwalden, Obwalden, Schaffhausen, Schwyz, Solothurn, St. Gallen, Thurgau, Uri, Zug, and Zürich). In the cantons of Bern, Fribourg and Valais, French is co-official; in the trilingual canton of Graubünden, more than half of the population speaks German, while the rest speak Romansh or Italian. In each case, all languages are official languages of the respective canton. While the French-speaking Swiss prefer to call themselves Romands and their part of the country is the Romandy, the German-speaking Swiss used to (and, colloquially, still do) refer to the French-speaking Swiss as "Welsche", and to their area as Welschland, which has the same etymology as the English Welsh (see Walha). Research shows that individuals with a French-sounding name in the German-speaking part suffer from social discrimination. Nevertheless, in 2017, 11.1%, or about 920,600 of the Swiss residents speak Standard German ("Hochdeutsch") at home, but this statistic is probably mainly due
