National Sample Survey (NSS)

Pooling of central and state sample data of NSS 68th round

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.

Subject Coverage

The 68th round (July 2011 – June 2012) of NSS was earmarked for survey of Household Consumer Expenditure (Schedule 1.0) and Employment and Unemployment (Schedule 10). The survey period of this round will be divided into four sub-rounds of three months duration. In each of these four sub-rounds equal number of sample villages/blocks (FSUs) will be allotted for survey with a view to ensuring uniform spread of sample FSUs over the entire survey period.

Objective of Pooling

One of the objectives of States participation in the NSS surveys is to provide a mechanism by which sample size will be increased and the pooling of the two sets of data would enable better estimate at lower sub state level, particularly at district level. At the State level, this will result in increased precision of the estimates and at disaggregated level, estimates will be more stable. But the major benefit will be derived in the case of estimates are generated at sub-state level like NSS region/districts.

Parameters considered for pooling

Considering the smaller sample size at district level, following broad parameters were considered for pooling.

  • a) MPCE of Food, Non-Food and Total MPCE derived from detail item from URP, MRP and MMRP
  • b) Household size, sex, age
  • c) Activity status principal with subsidiary, weekly, daily status and their intensity.

Summary findings of the pooled report on 68th round

As per the methodology suggested by the committee constituted by National Statistical Commission (NSC) on pooling of central and state sample data of National Sample Survey (NSS), the poolability tests have been conducted to test the central and state samples of NSS 68th round survey are coming from identical distribution function and the pooled estimates are generated in respect of Telangana State. The district wise pooled estimates of Monthly Per Capita Expenditure (MPCE) are presented below.
