India - Household Consumer Expenditure Survey, July 2007-June 2008, Shedule 1: 64th Round

Sample Design Outline of sample design: A stratified multi-stage design was adopted for the 64th round survey. The first stage units (FSU) were 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 had not been done, each individual town/ OG had been considered as an FSU. The ultimate stage units (USU) was 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.

Sampling Frame for First Stage Units: For the rural sector, the list of 2001 census villages (Panchayat wards for Kerala) constituted the sampling frame. For the urban sector, the list of latest available Urban Frame Survey (UFS) blocks and for non-UFS towns list of such towns/ OGs were considered as the sampling frame. Stratification: Within each district of a State/ UT, generally speaking, two basic strata was 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, within the urban areas of a district, if there were one or more towns with population 10 lakhs or more as per population census 2001 in a district, each of them formed a separate basic stratum and the remaining urban areas of the district were considered as another basic stratum. For a few districts, particularly in case of Tamil Nadu, if total number of towns in the district for which UFS is not done exceeds certain number, all such towns taken together to form another basic stratum. Otherwise, merged with the UFS towns for stratification.

Total sample size (FSUs): 12688 FSUs for central sample and 13624 FSUs for state sample had been allocated at all-India level. Allocation of total sample to States and UTs: The total number of sample FSUs is allocated to the States and UTs in proportion to population as per census 2001 subject to a minimum sample allocation to each State/ UT.


Weights (or multipliers) are given at the end of each record from 127th byte onwards. The weights (multipliers) are Sub-sample-wise, details of which are as given below : (For description of subsample, please see Instructions Manual for fiels staff, Vol-I) subsample-wise weights (multipliers) ---------------------------------------- NSS = Bytes 127-129 (3 bytes) NSC = Bytes 130-132 (3 bytes) MLT = Bytes 133-142 (10 bytes) ----------------------------------------- All records of a household /enterprise 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. In the value fields (Rs. or Quantity or Area etc.) only the numeric figure is given in datafile. The decimal point is to be assumed after looking at the type of that field in the printed schedule. Use of subsample-wise weights (multipliers) ---------------------------------------------------------------- For generating subsample-wise estimates based on data of all subrounds taken together, either Subsample-1 households /enterpeises or Subsample-2 households /enterprises are to be considered at one time. Subsample code is available in the data file. (Please see layout of data). Apply weight (or multipliers) as follows : For generating subsample-combined estimates based on data of all subrounds taken together all households/ enterprises are to be considered. Apply weight (or multipliers) as follows : weight = MLT/100, if NSS=NSC = MLT/200 otherwise
