The distribution of the national languages has seen moderate change over the past four decades. The proportions of German, Italian and Romansh spoken as people's main language(s) have fallen, whereas those of French and non-national languages have increased. English and Portuguese are the two non-national languages most frequently mentioned.

Between 1970 and 2019, the share of people who indicated German (or Swiss German) as their main language(s) declined from 66% to 62%. For Italian (including Ticino dialect and Italo-grison) and Romansh, the share also fell from 11% to 8% and from 0.8% to 0.5% respectively. On the other hand, the share of people who indicated French rose from 18% to 23% over the same period. 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.
