languages of cambodia

Compared to its neighbors and nearly every other country in the region, Cambodia has a relatively small number of languages. Nearly everyone speaks Khmer (Cambodian), which is the national language taught in schools, although about 1/3 of the population cannot read or write it due to poverty and lack of education. There are only a handful of other significant languages in the country. One is Vietnamese due to its border with Vietnam and immigration. Another is Min Nan Chinese (Hokkien), among the local Chinese community of several hundred thousand. Of the few main ethnic groups, the Cham have the largest number of non-Khmer speakers (several hundred thousand). Other ethnic groups and languages include the Jarai, Krung, Kuy, and Mnong (see map below).
