Analysis of information sources in references of the Wikipedia article "데시 (인도 아대륙)" in Korean language version.
Desi refers to the peoples indigenous to the precolonial Indian subcontinent, which is now comprised of several nation states that include India, Pakistan, Bangladesh, Bhutan, Nepal, Sri Lanka and Maldives.
But as South Asians have built up diasporic communities around the world, 'desi' has traveled with them, used not as a put-down but as an expression of ethnic pride. Make that pan-ethnic: Anyone with heritage from the subcontinent—India, Pakistan, or Bangladesh—can identify as a 'desi' and partake in 'desi' culture.
