The samples of the National Sample Survey Office are unlikely to be representative of Nagaland. This is so not because of the size of the sample, but because of the arbitrary restriction to villages within 5 kms of bus routes, whereas the bulk of the rural and tribal population is located farther from the roads. Further, it is argued that the Census of India data, which is used as the sampling frame, is found to be unreliable for Nagaland
