The Swiss franc is also the currency used for administrative and accounting purposes by most of the numerous international organisations that are headquartered in Switzerland.
Geography of Switzerland
Switzerland is also divided by language. There are four official languages: German (spoken by 63.7% of population), French (by 20.4% of population), Italian (by 6.5%) and Romansh (0.5%). From Bern east (except Ticino) the population generally speaks German. West of Bern, the population generally speaks French. In the southern Canton of Ticino, most people speak Italian. Romansh, a group of dialects descended from Vulgar Latin, is spoken in several regions in the canton of Graubünden.
