INDIA, October 18, 2018 (Centre for Policy Studies by Dr. J.K. Bajaj): The thirty-first note on the Religion Data of Census 2011 concerns the nearly complete Christianisation of the numerous tribes with their diverse geographies, diverse faiths and diverse ways of being that inhabit Mizoram, Manipur and Nagaland. All that social diversity seems to have been extinguished. The share of Hindus in all three States has declined rapidly among both the Scheduled Tribe and non-Scheduled Tribe communities.

In each of the three States, there are a very large number of diverse tribes often inhabiting geographical distinct districts or regions. All this diversity of beliefs, practices and ways of life has now been reduced to the uniformity of Christianity. Only a few followers of the Heraka faith remain among the Kabui of Manipur and the Zeliang of Nagaland as reminders and remnants of that diversity.

With the level of Christianity among the Scheduled Tribes having reached saturation levels, the direction of conversion seems to have shifted towards the non-Scheduled Tribes populations. In the last two decades, the share of Christians in the non-ST population of Mizoram has increased from 4.7 to 37.7 percent and that of Nagaland from 9.3 to 22.1 percent. In Manipur, it is the share of the ORPs rather than Christians that has recorded extraordinary increase from nearly nil to 13 percent in these two decades. The ORPs, as we have seen, are often a half-way house between Hinduism and Christianity. The share of Hindus in the non-ST population has declined everywhere, from 72.3 to 39.7 in Mizoram, from 87.7 to 69.5 percent in Manipur and from 74.5 to 59 percent in Nagaland.
