Results of censuses in India coupled with basic arithmetic show it will be nearly 220 years before the Muslim population in the country equals the Hindu population, according to Scroll.
Further, the latest census showed India's Hindus have dropped below 80 per cent of the population for the first time since independence and media had speculated the previous government deliberately delayed the release of the data because it showed a rise in the Muslim population, according to Reuters.
Members of Indian Prime Minister Narendra Modi's ruling Hindu nationalist party, which swept to power last year, have expressed growing concern about the rising numbers of Muslims.

The census data shows that Hindus declined to 79.8 per cent of the country's 1.2 billion people in 2011, from 80.5 per cent a decade earlier.
The share of Muslims rose to 14.2 percent from 13.4 percent in 2001 - the only major religious group to record a rise. Christians stayed at 2.3 percent and Sikhs fell to 1.7 per cent from 1.9 per cent.
Sakshi Maharaj, a Hindu priest-turned-politician, caused an uproar earlier this year when he said Hindu women should give birth to four children to ensure that their religion survives.
In the first census, conducted after Britain carved India and Pakistan out of colonial India in 1947, Hindus accounted for 84.1 per cent of the Indian population.
