The Socio-Economic Caste Census (SECC) that collected economic and caste data of households in 2011-12 will not be updated, sources said. Instead, the Centre will prepare a social registry of households with information on assets and benefits reaching them through government schemes. The registry will be drawn up using household data being collected under the ongoing population census.
