Switzerland sits at the crossroads of several major European cultures, which have heavily influenced the country's languages and cultural practices. Switzerland has four official languages--German, French, Italian, and Romansch (based on Latin and spoken by a small minority in the Canton Graubünden). The German spoken is predominantly a Swiss dialect, but newspapers and some broadcasts use High German. Many Swiss speak more than one language. English is widely known, especially among professionals.
More than 75% of the population lives in the central plain, which stretches between the Alps and the Jura Mountains and from Geneva in the southwest to the Rhine River and Lake Constance in the northeast. Resident foreigners and temporary foreign workers make up about 20% of the population.
Almost all Swiss are literate. Switzerland's 13 institutes of higher learning enrolled 99,600 students in the academic year of 2001-02. About 25% of the adult population holds a diploma of higher learning.
