Census enumerators came calling on the Bachchan household, prompting Amitabh to express his views on the issue of caste census.
"Wary of the sensitivity that this has raised recently by politicians, they keep away from it.
They reason that they would wait for some government decision on this. I tell them irrespective of what the system decides, my answer is ready - caste, Indian," he wrote on his blog.
Big B says that his father, Harivansh Rai Bachchan, a noted Hindi poet and litterateur, never believed in caste system.
"My Father never believed in caste and neither do any of us.
He married a Sikh (Teji Bachchan), I married a Bengali (Jaya Bhaduri), my brother a Sindhi (Ramola), my daughter (Shweta) a Punjabi (Nikhil Nanda), my son (Abhishek) a Mangalorean (Aishwarya Rai)... in his autobiography he (Harivansh Rai) had expressed that future generations of his family should marry into different parts of the country. So far that tradition has been kept alive!!"
Prime Minister Manmohan Singh has said the government will soon take a decision on caste-based census in the country.
Amitabh recounts the morning the enumerators came to his house.
"From the morning a consensus on the census. Officials from the BMC, the Bombay Municipal Corporation, troop into Prateeksha to detail in on information that shall for the first time in India develop for every citizen the UID - a Unique Identity Card.
"All kinds of information is sought name, place, age, dependents, place of birth, house, residence years and on. I wait for them to come to the crucial controversial one - caste. They don't."
Deputy leader of opposition in the Lok Sabha Gopinath Munde, Rashtriya Janata Dal (RJD) chief Lalu Prasad, Samajwadi Party (SP) chief Mulayam Singh Yadav and Janata Dal-United (JD-U) president Sharad Yadav are amongst those demanding that caste be registered during the census exercise.
