Bihar has become the first state to release data from a caste-based survey. 

• Total 63.1 per cent population is from Backward Classes.
• The report indicates 36 per cent of the population are from Extremely Backward Classes.
•  27.1 per cent are from Backward Classes, 19.7 per cent are from Scheduled Castes and 1.7 per cent are from Scheduled Tribes.
• The general population is 15.5 per cent. The state's total population is over 13.1 crore.
• The survey also said the Yadav community - the group to which Deputy Chief Minister Tejashwi Yadav belongs - is the largest sub-group, accounting for 14.27 per cent of all OBC categories.
• The report's fallout, which will almost certainly kick-up a political row, will likely also include calls to increase quotas for OBCs, which is capped now at 27 per cent. According to the data - released months before the 2024 Lok Sabha election, they are now 63.1 per cent of the state.
