In brief

The largest documented number lives in Czechia: 6,033,014 people in the 2021 census.

Official figures exist for 14 countries; together they add up to 6,081,054. This is not an estimate of the world total: the censuses were held in different years (2001-2022) and define belonging differently, and countries without such data are not counted.

In Russia's 2020 census (reference date 1 October 2021), 1,214 people identified with the nationality "Чехи" (Czechs)1. That is less than 0.01% of the 130,587,364 residents who stated a nationality.

Rosstat also assigns 2 other self-designations to this nationality (listed in Russian in the source table).

Main language: Czech. Glottolog classifies it in the Indo-European family.

Where they live: census figures

Each figure comes from the country's official census. Censuses define belonging differently (self-identification, citizenship, mother tongue, ancestry); the type is given on each row.
