Labels from the States sheet; no census share yet.

Official-language count: 4. Diversity below is country-level.

Mother tongue

Share of residents by the first language they learned, 2024.

How this is measured

Collective census categories (such as 'other languages') are left out, so shares can sum to less than 100%. Where a census lets people name several main languages, as Switzerland's does, they can sum to more.
