India - Household Consumer Expenditure, NSS 63rd Round : July 2006 - June 2007, NSS 63rd Round

Sample Design
A stratified multi-stage design has been adopted for the 63rd round survey. The first stage units (FSU) will be the 2001 census villages (Panchayat wards in case of Kerala) in the rural sector and Urban Frame Survey (UFS) blocks in the urban sector. In addition, for the newly declared towns and out growths (OGs) in census 2001 for which UFS has not yet been done, a separate list has been prepared and these list has been used as a frame for such towns and OGs in urban sector. For these towns and OGs the whole town/ OG will be considered as FSU. The ultimate stage units (USU) will be households/ service sector enterprises, in both the sectors. In the case of large villages/ towns/ blocks requiring hamlet-group (hg)/ sub-block (sb) formation, one intermediate stage will be the selection of hgs/ sbs from each FSU.

Sampling frame:
The list of villages as per census 2001 has been used as frame for the rural sector.
In the urban sector, three kinds of frames have been used:
(a) For the 27 towns with population 10 lakhs or more (as per Census 2001), EC-98 has been used as frame.
(b) For other UFS towns, the latest available list of UFS blocks has been used as frame.
(c) For non-UFS towns list of such towns/ OGs has been used as frame.

Stratification:
Within each district of a State/ UT, two basic strata were formed:
(i) rural stratum comprising of all rural areas of the district and
(ii) urban stratum comprising of all the urban areas of the district. However, if there were one or more towns with population 10 lakhs or more as per population census 2001 in a district, each of them also formed a separate basic stratum and the remaining urban areas of the district was considered as another basic stratum. There are 27 towns with population 10 lakhs or more at all-India level as per census 2001.

Formation of Second Stage Strata and allocation of households for schedule 1.0:
For rural sector in each selected village/ segments, three second stage strata (SSS) namely SSS 1, SSS 2 & SSS 3 are formed. Households with any member who worked for at least one day in any public works scheme of Govt. during last 365 days constitute SSS 1. Out of the remaining households SSS 2 and SSS 3 are formed on the basis of land possessed by household.

A cut-off point 'X' (in hectares) is determined at State/UT level from NSS 59th round data in such a way that top 20% of the rural households possessed land equal to or more than X. Out of the remaining (other than SSS 1) households all the listed households possessing land less than X will be in SSS 2 and the rest of the households will be in SSS 3.

For urban sector in each selected block/ segments, two second stage strata (SSS) namely SSS 2 & SSS 3 (there is no SSS 1 for urban sector) are formed on the basis of household MPCE.

In the urban sector, a cut-off point 'A' (in Rs.) is determined at NSS state-region level from NSS 61st round data in such a way that top 20% of the households had MPCE equal to or more than 'A'. All the listed households with MPCE less than 'A' will be in SSS 2 while the rest of the households will be in SSS 3.

From each SSS, the sample households were selected by SRSWOR.


There was no deviation from the original sampling design.


Two different weights have been provided in each file in the data set. Details are as follows:-

1. Weight for each sub sample is stored in the variable name : Wgt_SubSample
2. Combined subsample weight is stored in the variable name : Wgt_Combined
