"Hey I belong to Community X. How many people belong to my community in India?"
This might be a straightforward question in most parts of the world. But not in India.
As modern Indian census exercises do not report caste. Not since 1931 at least
"Tamil Brahmans - The Making of a Middle Class Caste" - which has some estimations, as well as "subcaste" info gleaned from 1891 census
I thought I should put it together
So at least for my community, one doesn't have to speculate
As per the authors, the worldwide Tamil Brahman population as of 2011 is 1.85 million
So let us look at the 1891 census, and extrapolate from there...
The 1891 census is particularly fascinating, as it has subcaste information
While among Sri-Vaishnavas, Vadakalais numbered 54K and Tengalais 40K
There was a huge Sri-Vaishnava community in Mysore, even back in 1891 which would not have been in this table
So I suspect the Sri-Vaishnava (Iyengar) population of 94K in 1891 is an under-estimation - I'd put it at 110-120K
130 years have elapsed since.
Indian population in 1891 was around 200MM, and today it is 1.35B - a ratio of 6.8
So let's take the ratio to be 5 for this demographic as opposed to 6.8
Which is significantly lower than the 1.9MM estimated by the authors of this book.
Of which I'd expect some 1.1 MM to be Smarthas, 600K to be Iyengars (based on the 1891 relative proportons) - as I dont see TFR patterns being too different for the two groups
The worldwide population of Tamil Brahmins is actually about the same as the population of Gurgaon today, or maybe the population of 3-4 large suburbs in Delhi / Bangalore
We need greater demographic clarity on the different Indian communities
Many groups today nurse an exaggerated sense of self-importance - as they don't quite realize how tiny they are in relation to the rest of the country
