Regular use of national languages
This indicator provides information on the regular use of none, one or more national languages. It therefore highlights Switzerland's multilingualism.
From an integration perspective, the aim is to increase the use of one or more national languages.
Key findings: The population without a migration background is more likely to have a national language in their linguistic repertoire than the population with a migration background. People with a migration background from the first generation were more likely not to mention a national language in their linguistic repertoire, while regular use of at least two national languages is more common in people from second or subsequent generations.
Trends over time: Since 2010, the percentage of people from the first generation not indicating a national language in their linguistic repertoire has increased. The percentage of people indicating a single national language in their linguistic repertoire has not significantly changed in the first generation, although it has increased in all the other population groups. Conversely, the percentage of people mentioning two or three national languages in their linguistic repertoire has declined across all population groups studied, but particularly among the second and subsequent generations.
