Patna, March 22 (IANS) Bihar plans to use photography and videography when it conducts a caste census from April 15.

Rural Development Minister Nitish Mishra said Bihar will be the first state to employ such technology.
Mishra told IANS that the census will be a paperless exercise as it will be done on hand-held electronic devices developed by the Bharat Electronic Development Corp.
It will drastically reduce data entry errors and enumerator discretion.
The caste census is being conducted after eight decades. In the general census undertaken every 10 years, only religious groups as well as Dalits and tribals are counted.
