The Madhya Pradesh government and the UN Children's Fund (Unicef) held a day-long workshop on the role of media in Census 2011.
It was announced that two pages on census related information had already been made on Facebook.
"While the centre's brand ambassadors are Sachin Tendulkar and actress Priyanka Chopra, lyricist Gulzar and television actress Divyanka Tripathi would be the brand ambassadors for census work in Madhya Pradesh," said Sachin Sinha, director of the directorate for census work.
"It is a real challenge for us to include everyone - from beggars to the elite class - in census," he said.
The second phase of Census 2011 will begin Feb 9 and continue till 28 across India.
