- v01: Edited, anonymous dataset for public distribution.
The survey covers the whole of the Indian Union except (i) Leh (Ladakh) and Kargil districts of Jammu & Kashmir, (ii) interior villages of Nagaland situated beyond five kilometres of the bus route and (iii) villages in Andaman and Nicobar Islands which remain inaccessible throughout the year.

A stratified multi-stage design has been adopted for the 59th round survey. The first stage unit (FSU) is the census village in the rural sector and UFS block in the urban sector. The ultimate stage units (USUs) are households in both the sectors. Hamlet-groups / sub-blocks constitute the intermediate stage whenever these are formed in the selected FSU.
Sampling Frame for First Stage Units:
For rural areas, the list of villages (panchayat wards for Kerala) as per Population Census 1991 and for urban areas the latest UFS frame have been used as sampling frame. For stratification of towns by size class, provisional population of towns as per Census 2001 have been used.
Two special strata have been 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 was formed whenever at least 50 such FSUs were found in a State/UT. Similarly, special stratum 2 was formed if at least 4 such FSUs were found in a State/UT. Otherwise, such FSUs were merged with the general strata.
From FSUs other than those covered under special strata 1 & 2, general strata were formed and its numbering started from 3. Each district of a State/UT was normally treated as a separate stratum. However, if the census rural population of the district was greater than or equal to 2 million as per population census 1991 or 2.5 million as per population census 2001, the district was split into two or more strata by grouping contiguous tehsils. However, in Gujarat, some districts were not wholly included in an NSS region. In such cases, the part of the district falling in an NSS region constituted a separate stratum.
Urban Sector: In the urban sector, strata have been 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 city with population 10 lakhs or more
The stratum numbers remained as above even if, in some regions, some of the strata did not exist.
Total Sample Size (FSUs):
10608 FSUs have been allocated at all-India level on the basis of investigator strength in different States/UTs for central sample and 11496 for state sample.
Allocation of Total Sample to States and UTs:
The total number of sample FSUs has been 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 size has been 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. would not exceed the rural sample size. Earlier practice of giving double weightage to urban sector has been modified considering the fact that two main subjects of enquiry (sch. 18.1 and sch 33) are rural based and there has been considerable growth in urban population over the years. More samples have been allocated to rural sector of Meghalaya state sample at the request of the DES, Meghalaya.
Allocation to Strata:
Within each sector of a State/UT, the respective sample size was allocated to the different strata in proportion to the stratum population as per census 2001. Allocations at stratum level was adjusted to a multiple of 2 with a minimum sample size of 2. However, a multiple of 4 FSUs was allocated to a stratum wherever possible.
Selection of FSUs:
FSUs were 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 was done using Simple Random Sampling without replacement (SRSWOR). Samples were drawn in the form of two independent sub-samples both in rural and urban sectors.
Selection of Hamlet-groups/Sub-blocks / Households
Formation of Hamlet-group/Sub-block:
Large villages/blocks having approximate present population 1200 or more are divided into a suitable number of hamlet-groups/sub-blocks.
less than 1200 1 (no hamlet-groups/sub-blocks formation)
1200 to 1799 3
1800 to 2399 4
2400 to 2999 5
3000 to 3599 6
For rural areas of Himachal Pradesh, Sikkim, Nagaland and Poonch, Rajouri, Udhampur, Doda districts of Jammu and Kashmir, the number of hamlet-groups formed is
less than 600 1 (no hamlet-groups/sub-blocks formation)
600 to 899 3
900 to 1199 4
1200 to 1499 5
Hamlet-groups / sub-blocks are formed by more or less equalising population. Two hamlet-groups / sub-blocks are selected from a large village or block by SRSWOR. Listing and selection of the households are done independently in the two selected hamlet-groups/sub-blocks so formed.
Two SSS are formed:
SSS 1: households possessing land < Y
SSS 2: households possessing land = Y
SSS 1: households belonging to MPCE classes 1, 2 and 3
SSS 2: households belonging to MPCE class 4
Out of the four households selected for sch. 1.0, two households are covered in visit 1 and two in visit 2.
Allocation and Selection of Sample Households:
Two households are selected from each SSS of each type of schedule. In case of hamlet group/ sub-block formation, one household is selected from each (hg/sb) × SSS. Sample households for each type of schedule are selected by SRSWOR in each SSS of each hg/sb.
