How to read the map. Each colour is a language family: a group of languages that share a common ancestor. The ten largest families have their own colour and every other family is grey. Areas are see-through, so where two languages share a place the colours mix. Tap anywhere to list every language whose area covers that spot. Areas are generalisations drawn from published atlases, many of them decades old, and cities are multilingual, so an area never says that everyone there speaks the language. A dot marks a language that has no area map. The family name is always given in words, because colour alone is hard to tell apart for some people.

Where Czech is spoken

Czech is spoken in 4 countries: Czechia, Slovakia, Austria and Poland. The table gives the share of each country’s people who speak it, from Unicode CLDR, where CLDR has a figure.

CountryShare of populationEstimated speakers
Czechia98%10,621,142
Slovakia47%2,614,916
AustriaNot givenNot given
PolandNot givenNot given

Estimated speakers are the CLDR percentage applied to CLDR’s own population figure for the country, so they are rough. A country without a figure may still have speakers: it is listed because the language area, or Glottolog’s record, reaches it.

On the map, Czech is drawn as an area from Asher and Moseley 2007. The area was digitised by the Glottography project (doi:10.5281/zenodo.18613195), and the atlas is cited on the data sources page. Language areas are generalisations, and cities and borderlands are multilingual, so the outline does not mean that everyone inside it speaks Czech.

How many people speak Czech?

Wikidata gives about 10.7 million first-language speakers (Ethnologue, 2019). These figures are approximate: they come from different sources, years and definitions of a speaker.

Status: Not endangered. Glottolog lists it as not endangered: it is still being passed on to children.
