Explanation:

JD (U) party in Bihar passed resolutions calling for caste census to be conducted in India. Many parties across the political spectrum have supported this proposal. So far, the Government of India has decided as a matter of policy not to enumerate caste-wise populations other than SCs and STs in Census.

Every Census in independent India from 1951 to 2011 has published data on Scheduled Castes and Scheduled Tribes, but not on other castes. Before that, every Census until 1931 had data on caste.
