Outline of sample design: A stratified multi-stage design has been adopted for the 60th round survey. The first stage units (FSU) will be the 1991 census villages in the rural sector and Urban Frame Survey (UFS) blocks in the urban sector. The ultimate stage units (USU) will be households in both the sectors. In case of large villages/blocks requiring hamlet-group (hg)/sub-block (sb) formation, one intermediate stage will be the selection of two hgs/sbs from each FSU.
Sampling Frame for First Stage Units: For the rural sector, the list of Census 1991 villages (panchayat wards for Kerala) and Census 1981 villages for J & K will constitute the sampling frame. For the urban sector, the list of latest available Urban Frame Survey (UFS) blocks will be considered as the sampling frame.
Rural sector: Two special strata will be formed at the State/ UT level, viz.
Stratum 1: all FSUs with population between 0 to 50 and
Stratum 2: FSUs with population more than 15,000.
Special stratum 1 will be formed if at least 50 such FSUs are found in a State/UT. Similarly, special stratum 2 will be formed if at least 4 such FSUs are found in a State/UT. Otherwise, such FSUs will be merged with the general strata.
From FSUs other than those covered under special strata 1 and 2, general strata will be formed and its numbering will start from 3. Each district of a State/UT will normally be treated as a separate stratum. However, if the census rural population of the district is greater than or equal to 2.5 million as per population census 2001 or 2 million as per population census 1991, the district will be split into two or more strata, by grouping contiguous tehsils to form strata. However, in Gujarat, some districts are not wholly included in an NSS region. In such cases, the part of the district falling in an NSS region will constitute a separate stratum.
Urban sector: In the urban sector, strata will be formed within each NSS region on the basis of size class of towns as per Population Census 2001. The stratum numbers and their composition (within each region) are given below.
stratum 1: all towns with population less than 50,000
stratum 2: all towns with population 50,000 or more but less than 2 lakhs
stratum 3: all towns with population 2 lakhs or more but less than 10 lakhs
stratum 4, 5, 6,...: each town with population 10 lakhs or more
The stratum numbers will remain as above even if, in some regions, some of the strata are not formed.
Total sample size (FSUs): 7612 FSUs have been allocated at all-India level on the basis of investigator strength in different States/UTs for central sample and 8260 for state sample.
Allocation of total sample to States and UTs: The total number of sample FSUs is allocated to the States and UTs in proportion to provisional population as per Census 2001 subject to the availability of investigators ensuring more or less uniform work-load.
Allocation of State/UT level sample to rural and urban sectors: State/UT level sample is allocated between two sectors in proportion to provisional population as per Census 2001 with 1.5 weightage to urban sector subject to the restriction that urban sample size for bigger states like Maharashtra, Tamil Nadu etc. should not exceed the rural sample size. Earlier practice of giving double weightage to urban sector has been modified considering the fact that there has been considerable growth in urban population. A minimum of 8 FSUs will be allocated to each state/UT separately for rural and urban areas.
Allocation to strata: Within each sector of a State/UT, the respective sample size will be allocated to the different strata in proportion to the stratum population as per census 2001. Allocations at stratum level will be adjusted to a multiple of 4 with a minimum sample size of 4.
Selection of FSUs: FSUs will be selected with Probability Proportional to Size With Replacement (PPSWR), size being the population as per Population Census 1991 in all the strata for rural sector except for stratum 1. In stratum 1 of rural sector and in all the strata of urban sector, selection will be done using Simple Random Sampling Without Replacement (SRSWOR). Within each stratum, samples will be drawn in the form of two independent sub-samples in both the rural and urban sectors.

Data Collection Mode
Schedule 1.0 - Consumer Expenditure
Schedule 1.0 has been split into several blocks to obtain detailed information on the expenditure incurred on domestic consumption and other particulars of the sample household.
- Block 0 - Descriptive identification of sample household: This block is meant for recording descriptive identification particulars of a sample household.
- Block 1- Identification of sample households: This block is meant for recording the identification particulars of the sample FSU in terms of codes or numbers.
- Block 2- Particulars of field operations: The identity of the Investigator, the Assistant Superintendent and the Superintendent associated with the work, date of survey/inspection/scrutiny of schedules, date of despatch, etc., have been recorded in this block against the appropriate items in the relevant columns.
- Block 3- Household characteristics: The characteristics to be recorded in this block are mainly intended to be used to classify the households for tabulation.
- Block 4- Demographic and other particulars of household members: All members of the sample household will be listed in this block. Demographic particulars (relation to head, sex, age, marital status and general education) and number of meals taken will be recorded for each member using one line for one member.
- Block 5- Consumption of cereals, pulses, milk, sugar and salt during the last 30 days: In this block information on consumption of each item of cereals, pulses, milk, sugar and salt by the household will be collected for a reference period of 30 days preceding the date of survey in both types of schedule.
- Block 6- Consumption of edible oil, egg, fish and meat, vegetables, fruits, spices, beverages and processed food and pan, tobacco and intoxicants during the last 30/7 days: The information on consumption of edible oil, egg, fish and meat, vegetables, fruits, spices, beverages and processed food and pan, tobacco and intoxicants will be collected through this block.

- Block 8- Consumption of clothing, bedding, etc. during the last 365 days: In this block, information on quantity and value of consumption of all items of clothing will be collected. The information in this block is required to be collected for a reference period of last 365 days. Consumption of clothing is defined as an item of clothing being brought into first-use.
