India - Land and Livestock Holdings Survey: NSS 48th Round, Schedule 18.1, January - December 1992: Visit - 2

The sample design adopted for the survey was essentially a stratified two stage design, with census villages and urban blocks as first stage units (FSUs) for the rural and urban sectors respectively, and households as the second stage sampling units (SSUs) in both the sectors. The
selection of villages was done with probability proportional to population (with replacement), mainly based on the 1981 census list of villages. The selection of urban blocks was done with equal probability without replacement based on Urban Frame Survey (UFS) conducted by the NSSO as an on-going activity.
The details of sample design and estimation procedure adopted for the survey are given in chapter-2 of the Report 407 attached as external attachment.

There was no deviation from the original sample deviation.

In all 9052 villages were planned to be surveyed in this round. Of these, 4328 villages were allocated to the central sample - the part surveyed mainly by the NSSO field staff - and the rest to the state sample - the part surveyed by the state agencies. In the urban sector, the allocations for the central and state samples were 2484 and 3076 blocks respectively.
The number of villages and urban blocks actually surveyed under the central sample was 4231 and 2420 respectively.
Sample size - second stage units :Plan was to survey 8 households from each sample village and 9 households from each sample urban
block. In the central sample, the actual number of households surveyed was 33289 in the rural sector and 20592 in the urban sector.
Sample weights were calculated and included in each of the data files
Variable 'Wgt_SS' refers to Multiplier for each Subsample.
Variable 'Wgt_Combined' refers to Combined Multiplier.
