In the multi-subject integrated National sample surveys of NSSO, a large number of technical terms have been used. The explanation of these terms, their definitions and the underlying concepts were documented and published in January 1980 issue of Sarvekshana for the first time and later released as a “Glossary” in 1981. Again in the year 2000 an updated version of the same was released as the Golden Jubilee publication ‘Concepts and Definitions Used in NSS’. These are however confined to socio-economic topics and exclude terms used in the Annual Survey of Industries, price-collection work and crop surveys. In recent rounds of NSS surveys some more modifications have been made in these technical terms.
