The distribution of the national languages has seen moderate change over the past five decades. The proportions of German, Italian and Romansh spoken as people's main language(s) have fallen, whereas that of French has increased.
The share of people who indicated a non-national language increased sharply, mainly due to the possibility, as of 2010, of indicating several main languages. English and Portuguese are the two non-national languages most frequently mentioned.
On the labour market, Swiss German is the most frequently used language (63% of employed persons), followed by German (standard language) (34%), French (28%), then English (21%), and Italian (8%).
45% of the employed population in Switzerland use more than one language in their work at least once a week.
English is the language that the employed population would like to learn or improve the most for their work: it is ahead of the three national languages, German, French and Italian. Other languages cited in this context are Spanish, Chinese, Russian and Swiss German.
At home or with friends and family, 57% of all persons interviewed usually speak Swiss German, 23% French, 11% German, 8% Italian. English and Portuguese are the two non-national languages most often mentioned with 6% and 4% respectively.
More than two thirds of the permanent resident population aged 15 or over (68%) use more than one language at least once a week, for example, to communicate with friends or family, at work or for media consumption during leisure time.
Among persons aged 25 or over, one in five learns a second language. English is the most frequently learned language in all language regions (among all apprentices, 34% specify this language), far ahead of French and German (15% each), Spanish (11%) and Italian (9%).
