"Immigration from Bangladesh is of two types. Firstly there are members of the minority communities fleeing occasional waves of per­secution or the more general sense of being second-class citiz­ens under the Islamic dispensation. Few Hindus would disput­­­­­­­­­­­­­­­­­­e their right to settle down in India. Secondly, there are Mus­lims seek­ing econom­­ic oppor­tunities or sheer living space, which dirt-poor and inten­sely overc­rowded Banglad­esh cannot offer to the ever-larger num­bers of newcomers on the hous­ing and labour market... The BJP argues that refugees from persecution and illegal economic migrants merit a different treat­ment, as is assumed in the arrangements for refugee relief of most countries. But sec­ularists see it differently, for "unlike the BJP, the Congre­ss (I) views both Hindus and Muslim from Bangladesh as in­filtrat­ors". Terminology is a part of the problem here, with secularists systematically describing Hindu refugees as "migrants" if not "infiltrators", and Muslim illegal immigrants as "refugees"... The Hindu population in East Bengal had declined from 33% in 1901 to 28% in 1941. It fell to 22% by 1951 due to the Partition and the post-Partition exodus, and to 18.5% in 1961. By 1971, it had fallen to 13.5%, partly due to the 1971 massacre by the Pakistani Army, partly due to intermittent waves of emigrati­on. The 1981 figure was 12.1%. In 1989 and 1990, due to "large-scale destru­ction, desecration and damage inflic­ted on Hindu temples and religious institutions", "clandestine migrat­ion­­­ by the Hindus to India went up"."
