Almost 97% of Bhutanese refugees are ethnic Nepalis. The non-Nepalis include the Charchop, Drukpa, Urow, and Khenpga ethnic groups. Nearly all refugees speak Nepali as a first or second language. UNHCR estimates that about 35% of the population has a functional knowledge of English.
In Kansas, at the end of 2014, Nepali-speaking Bhutanese constituted 24% of the overall refugee settlement population (Catholic Charities of Northeast Kansas, 2015).
