India - Employment, Unemployment and Migration Survey: NSS 64th Round, Schedule 10, July 2007 - June 2008

A stratified multi-stage design was adopted for the 64th round survey. The first stage units (FSU) were the 2001 census villages (Panchayat wards in case of Kerala) in the rural sector and Urban Frame Survey (UFS) blocks in the urban sector. However, for the newly declared towns and out growths (OGs) in Census 2001 for which UFS were not done, each individual town/ OG were considered as an FSU. The ultimate stage units (USU) were the households in both the sectors. In case of large FSUs, i.e. villages/ towns/ blocks requiring hamlet-group (hg)/ sub-block (sb) formation, one intermediate stage was the selection of two hgs/ sbs from each FSU. Details of the sample design and estimation procedure is given as a document in external resource .

There was no deviation from the original sample deviation.

At the all-India level, 12,688 FSUs (7,984 villages and 4,704 urban blocks) was allocated for survey. Out of these 12,688 FSUs allotted for survey, 12,589 FSUs could be surveyed – 7,921 in rural and 4,668 in urban. A sample of 10 households was planned for survey from each selected village and urban block.The survey covered a sample of 1,25,578 households (79,091 in rural areas and 46,487 in urban areas) and a sample of 5,72,254 persons (3,74,294 in rural areas and 1,97,960 in urban areas).
For generating any estimate, one has to extract relevant portion of the data, and aggregate after applying the weights.

Weights (or multipliers) VARIABLES are given at the end of record of each dataset. The weights (multipliers) are
WGT_SS for Sub-sample-wise estimation and WGT_Combined for combined subsample estimates.

All records of a household will have same weight figure. In case of those Blocks/Levels, where Item/Person Sl.No. is not applicable the field is filled up with 00000.

Use of subsample-wise weights (multipliers)

For generating subsample-wise estimates based on data of all subrounds taken together, either Subsample-1 households or Subsample-2 households are to be considered at one time. Subsample code is available in the dataset For generating subsample-combined estimates based on data of all subrounds taken together all households are to be considered.
