The linguistic landscape in Switzerland has changed over the past 40 years, a long-term report has found. German (and Swiss German), Italian and Romansh have declined, while French and non-national languages have gained momentum since the 1970s.
The proportion of people who speak Swiss German first and foremost fell from 66% to 63% between 1970 and 2016, according to the figures published by the Federal Statistical Office external linkon Wednesday.
The number of Italian and Romansh speakers also fell – from 11% to 8% and from 0.8% to 0.5% respectively.
By contrast, the proportion of French speakers in the country rose from 18% to 23% over the same time period.
The proportion of people who did not speak a Swiss national language as their mother tongue increased significantly: from 4% in 1970 to 22% in 2016.
The statistical office said this increase was related to a change in the questionnaire which made it possible for people to name several main languages since 2010. English and Portuguese were the two foreign languages mentioned most often.
