[1] Tilung is spoken by a few elderly people living in several small settlements in Chyasmitar (च्यास्मिटार) Village Development Committee (VDC), southern Khotang (खोटाङ) district, Sagarmatha Zone, Nepal (Opgenort 2011, Ethnologue).
It is located on the northern bank of the Sunkosi (सुनकोशी) River, on the last ridge of the Halesi Range.
According to the 2001 Census of Nepal (with data from 1991), Chyasmitar VDC had a population of 2,167 persons living in 412 households, and there were 310 speakers of Tilung.
However, Opgenort's (2011, 2013) more recent investigations have shown that there are only a few fluent speakers of Tilung remaining.
These people are all older than 60 years and fully bilingual in Nepali, which is the dominant language among the Tilung ethnic community.
