Muslims in India accounted for 9.9 per cent (of India’s population) in 1951, 10.8 per cent in 1971 and 11.3 per cent in 1981, and presumably about 12… - T. V. Rajeswar

A study of the border belt of West Bengal yields some telling statistics: 20-40 per cent villages in the border districts are said to be predominantly Muslim. There are indications that the concentration of the minority community, including the Bangladesh immigrants, in the villages has resulted in the majority community moving to urban centres. Several towns in the border districts are now predominantly inhabited by the majority community but surrounded by villages mostly dominated by the minority community. Lin Piao’s theory of occupying the villages before overwhelming the cities comes to mind, though the context is different. However, the basic factor of security threat in both the cases is the same.

The Kishanganj district (of Bihar), which was part of Purnea district earlier, which is contiguous to the West Bengal area, also has a majority of Muslim population.

There is a distinct danger of another Muslim country, speaking predominantly Bengali, emerging in the eastern part of India in the future, at a time when India might find itself weakened politically and militarily.
