Before the advent of the Covid-19 pandemic, the world was notionally divided between north and south. The developed countries were aggregated as the north, and the south as developing and underdeveloped countries. If India is considered to be in the south, then Bihar is south of the south. In other words, Bihar is the most underdeveloped part of India. In some sense, Bihar can be referred to as the Appalachian region of India.
