Differing views within the government on the issue had come to the fore at a meeting of the cabinet earlier this month when Prime Minister Manmohan Singh had decided to continue discussion on the matter.
Those opposing caste-based census believe that it is a throwback to the medieval times and the census should be looking at the future and not the past.
Political parties, including the Samajwadi Party, RJD and JD-U have been strongly demanding inclusion of caste in the census exercise.
The issue had figured prominently in the just-concluded budget session of Parliament when the Prime Minister had assured the members that government would take their views into account before deciding on the matter.
"I made a statement in Parliament in which I said that we shall take into account the views expressed in Parliament by various sections... and that I will ask the Cabinet to consider them. That process is on," Singh had said replying to a question on the issue.
Caste-based census was last conducted in the country in the year 1931.
