The Jammu and Kashmir Police have begun a census of residents here to build a database to help them keep an eye on miscreants who may foment trouble.
Cops are visiting houses to collect details of residents, police sources said.
Besides the number of persons living in a particular dwelling, they will also seek details about the occupation of residents.
The exercise has been undertaken particularly in areas which have been notorious for street protests during the 2008-09 turmoil, the sources said.
Efforts are being made to keep a check on tenants living in rented homes to ensure that non-state elements are unable to establish a base in the city, they said.
Militants had attacked two police stations in the past week causing concern over ultras` attempt to revive militancy in the region.
Moreover, the data will also help in gauging the extent of unemployment in these areas so that police recruitment drives can be better focused, the sources said.
