In brief
The largest documented number lives in China: 11,624,257 people in the 2020 census.
Official figures exist for 6 countries; together they add up to 11,965,827. This is not an estimate of the world total: the censuses were held in different years (2001-2021) and define belonging differently, and countries without such data are not counted.
In Russia's 2020 census (reference date 1 October 2021), 2,217 people identified with the nationality "Уйгуры" (Uyghurs)1. That is less than 0.01% of the 130,587,364 residents who stated a nationality.
Main language: Uighur. Glottolog classifies it in the Turkic 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.
