And just for your knowledge - read page 32 and page 160 of the Sachar report on demographics and poverty levels. In Bengal - while the general population has a poverty level 0f 6% ; that for muslims is 27% in urban areas. gap elsewhere in rural areas is more. This is because the Bangaladeshi migrants form a big % of minorities in Bengal and they are poor and illiterate. Comparison in Kerala is silly because everyone there is fully educated local people.
