In brief
The largest documented number lives in Russia: 16,200 people in the 2021 census.
Official figures exist for 2 countries; together they add up to 16,203. This is not an estimate of the world total: the censuses were held in different years (2021-2021) and define belonging differently, and countries without such data are not counted.
In Russia's 2020 census (reference date 1 October 2021), 16,200 people identified with the nationality "Чукчи" (Chukchis)1. That is 0.01% of the 130,587,364 residents who stated a nationality.
Rosstat also assigns 4 other self-designations to this nationality (listed in Russian in the source table).
Main language: Chukchi. Glottolog classifies it in the Chukotko-Kamchatkan 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.
