A comprehensive socio economic survey of Brahmins would be taken up by the AP Brahmin Welfare Corporation, said coordinator Siripurapu Sridhar in Guntur on Monday. He said that Chief Minister N. Chandrababu Naidu had sought a comprehensive survey of each Brahmin family in all 175 constituencies in the State. The members of the survey team would visit each house with a four-page questionnaire on their socio, educational, health and economic status and would come out with a report within four months, he added.
