An all-party delegation from Bihar; led by Chief Minister Nitish Kumar, met Prime Minister Narendra Modi recently to demand a caste census in India.

How do intra-caste socio-economic variations further complicate the debate? In this video, Gilles Verniers and D Shyam Babu unpack these questions and shed light on the need to collect data in a non-partisan way.
