India - Household Consumer Expenditure: NSS 48th Round, Schedule 1, January - December 1992

The sample design adopted for the survey was essentially a stratified two-stage one for both rural and urban areas. The census villages and urban blocks were the first stage units (FSUs) for the rural and urban sectors respectively, while households were the second stage sampling units (SSUs) for both the sectors. The selection of villages was done with probability proportional to population (with replacement), based mainly 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 on an on-going basis.

Sample size - first stage units: In all, 9052 villages were planned to be surveyed in this round. Of these, 4328 villages were allocated to the central sample which was the part surveyed mainly by the NSSO field staff. The remaining villages were allocated to the state sample, which was the part to be surveyed by the state agencies. In the urban sector, the allocations for the central and state samples were 2484 and 3076 respectively.

Sample size - second stage units: For the AIDIS, 9 households from every sample village and every urban block were planned to be surveyed. In the central sample, the actual number of households surveyed was 36425 in the rural sector and 20606 in the urban sector.
