The much publicized ongoing exercise of the headcount of social groups in Bihar by the state government has run into fresh controversy over enumeration of members of 'third gender' as a separate caste. Castes in Bihar will now be identified on the basis of codes, in the form of numbers, and each caste has been given a numerical code for use during the month-long second phase of caste-based headcount from April 15 to May 15. For instance, the sub-categories of Maithil, Kanyakubj and other Brahmins have been merged into a single social entity called Brahmin, which will have caste code as 126. No separate enumeration of its sub-categories will be done.
