National Sample Survey (NSS)

National Sample Survey (NSS)

Introduction

The National Sample Survey (NSS) was set up in 1950, to bridge large gaps in statistical data needed for planning, policy formulation and computation of national income aggregates, especially in respect of the unorganized and household sector of the economy. NSSO has been conducting nationwide multi-subject, integrated, large scale sample surveys in the form of successive rounds covering various aspects of social, economic, demographic, industrial and agricultural statistics. The surveys are being conducted in rounds of normally one year duration comprising four sub rounds of three months duration each.

The states have been participating in the NSS surveys on equal matching sample from 14th round (1958) onwards by using the same concepts, definitions and procedures and by adopting the same sample design based on independently drawn sample as that of NSSO. The DES has been participating on equal matching sample up to 66th round and double the sample size from 67th round onwards.
