Incorrect estimate With zero data from actual Indian Govt census
Shia Muslims are a large minority among
India's
Muslims.
There has been no particular census conducted in India with regards to sects, but Indian sources claimed the Shia population in mid 2005–2006 was between 25% and 31% of the entire Muslim population of India which accounts them in numbers between 40,000,000
[1][2] to 50,000,000 plus
[3] of the then 157 million Indian Muslim population
That's 50 million in 2005-2006 itself
India's Shia population in early 2000 was around 30 million with
Sayyids comprising just a tenth of the Shia population.

According to some national and international sources Indian Shia population is the world's second-largest after
Iran.
