This article analyses prevalence estimates for disability from the 58th round of the National Sample Survey (2002) and Census 2001. Because of the substantial differences in rates of disability between these two sources, it looks at the possible sources of these discrepancies. Part of the differences could be explained by differences in the definition of disability and disability types. Besides, both the NSS and the census provide only limited information about disability. Refinements are needed in each of the data sources so that they may capture different aspects and implications of disability.
