Now I would like to draw the attention of the House to the Census Report of 1931, Vol. III, Part 1, page 219, wherein it is stated :–
“The total for the exterior castes, i.e., Scheduled Caste-of Sylhet is therefore 392,000 at a minimum. and for Cachar 80,000 and the total for the whole of the Surma Valley is 472,000 at a minimum. For the Assam and Surma Valley together the total is 655,000 and for the whole province is 657,000.”
