Hindkowans (Hindko: هِندکوان (Shahmukhi), हिन्दकोवान (Devanagari), ਹਿੰਦਕੋਵਾਨ (Gurmukhi)) or known locally as "Chachi's" are an Indo-Aryan ethno-linguistic group native to the Khyber-Pakhtunkhwa and Punjab provinces of Pakistan. However, an indeterminate number have left the region and now live in other parts of South Asia,[9] such as the Indian state of Jammu & Kashmir.[4]
Hindkowans speak Hindko, a Lahnda language,[10] and is native to the northern regions of Pakistan primarily concentrated in the Hazara division, and urban centers of Khyber Pakhtunkhwa province of Pakistan such as Peshawar, Kohat and Mansehra. It is for this reason that alternatively, the term "Kharian/Kharay or city-dweller" maybe sometimes be used for the Hindkowan.
