Socio-Economic/Monitoring Survey [hh/sems]
The National Sample Survey (NSS), set up by the Government of India in 1950 to collect socio-economic data employing scientific sampling methods, will start its fifty-eighth round from 1st July 2002.
The fifty-eighth round of NSS is earmarked for collection of data on disability, housing condition, village facilities and slum particulars besides that on household consumer expenditure and employment-unemployment. The field operations of the survey will commence on 1st July 2002 and will continue up to 31st December 2002.
The National Sample Survey made its first attempt to collect information on the number of physically disabled persons during 15th round (July 1959 - June 1960). Thereafter, data on disabled persons were collected in the 16th (July 1960 - June 1961), 24th (July 1969 - June 1970), 28th (October 1973 - June 1974), 36th (July - December, 1981) and 47th (July - December, 1991) rounds. The surveys undertaken during 15th, 16th, 24th and 28th rounds were intended mainly to get a count of the disabled persons of various kinds. In the surveys undertaken during the 36th and 47th rounds, detailed inquiry was made on each type of disability along with the socio-economic characteristics of the disabled.
Housing condition of the people is one of the very important indicators of the socio-economic development of the country. Statistical data on housing condition in qualitative and quantitative terms are needed periodically for an assessment of housing stock and formation of housing policies and programmes. NSS, therefore, started collecting data on housing condition of the dwelling units and basic housing amenities available to them from its 7th round (October 1953 - March 1954) to the 23rd round (July 1968 - June 1969) with the exception in the 13th and 14th rounds. A comprehensive survey on housing condition was first carried out in the NSS 28th round (October 1973 - June 1974) in the rural and urban areas of the country with a sample size of about 1.2 lakh households. The next comprehensive survey on housing condition was carried out in the NSS 44th round (July 1988 - June 1989). The relevant information was collected in detail in a separate schedule canvassed to about 74,000 sample households.
A similar comprehensive survey on housing condition was conducted in the NSS 49th round along with a survey on migration, broad information on which is now being collected quinquennially as a part of the employment-unemployment survey. However an integrated schedule viz. schedule 1.2: housing condition and migration was designed for collecting data on 'housing condition' as well as 'migration'. The design was formulated in such a way that the households living in the slums were adequately represented in the sample of households where the integrated schedule was canvassed. In addition, a schedule, viz. schedule 0.21: particulars of slum was also framed to collect selected information about each of the slums in the sample villages/blocks. Earlier a nation-wide survey on the 'economic condition of slum dwellers in urban cities' was conducted in the NSS 31st round (July 1976 - June 1977).
The fifty-eighth round of NSS will cover disability (both physical and mental), housing conditions, village facilities and slum particulars. In addition, the annual consumer expenditure enquiry covering some key characteristics of employment-unemployment will also be carried out on a sample of four households in each sample FSU.
The survey covered both mental and physical disabilities. Among the physical disabilities speech, hearing, visual and locomotor disabilities were considered. The other major topics covered were housing conditions, village facilities, slum particulars etc. In addition, the annual consumer expenditure enquiry covering some key characteristics of employment-unemployment were also carried out on a sample of four households in each sample FSU.

Sampling
Outline of Sample Design:
A stratified multi-stage design was adopted for the conduct of survey of NSS 58th round. The first-stage units were census villages (panchayat wards for Kerala) in the rural sector and the NSSO Urban Frame Survey (UFS) blocks in the urban sector.
Sampling Frame for First-Stage Units:
The ultimate stage units were households in both the sectors. For the rural sector, the list of Census 1991 villages (panchayat wards for Kerala) and Census 1981 villages for J & K constituted the sampling frame. For the urban sector, the list of latest available Urban Frame Survey (UFS) blocks was considered as the sampling frame.
Stratification
Rural sector: Two special strata were formed as given below at the State/ UT level on the basis of Population Census 1991 viz.
Stratum 1: all FSUs with population between 0 to 50, and
Stratum 2: FSUs with population more than 15,000
The special stratum 1 was formed if at least 50 such FSU's 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 the remaining FSUs (not covered under stratum 1 &2) general strata (hereafter, stratum will refer to general stratum unless otherwise mentioned) was formed and numbered 3, 4, 5 …. etc. (even if no special strata have been formed). Each district of a State/UT was normally treated as a separate stratum. However, if the provisional population of the district was greater than or equal to 2.5 million as per Census 2001, the district was divided into two or more strata with more or less equal population as per population census 1991 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, stratum was formed within each NSS region on the basis of size class of towns as per Census 1991 town population except for towns specified in Table 4. The stratum number and their composition (within each region) are given below:
stratum 1: all towns with population (P) < 0.1 million
stratum 2: all towns with 0.1= P < 0.5 million
stratum 3: all towns with 0.5= P < 1 million
stratum 4,5,6, … each town with P= 1 million
Sub-stratification:
There was no sub-stratification in the rural sector. However, to cover more number of households living in slums, in urban sector each stratum was divided into 2 sub-strata as follows:
sub-stratum 1: all UFS blocks having area type 'slum area'
sub-stratum 2: remaining UFS blocks
If there was one UFS block with area type 'slum area' within a stratum, sub-stratum 1 was not formed; it was merged with sub-stratum 2.
Total sample size (FSUs):
A total number of 8338 and 9076 first-stage units were selected for survey in the Central and State samples respectively.
Allocation of total sample to States and UTs:
The total sample FSUs was 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 was allocated between two sectors in proportion to provisional population as per Census 2001 with double weightage to urban sector.
Allocation of Rural /Urban sector level sample size to strata / sub-strata:
Both rural and urban sector samples allotted to a State/UT were allocated to different strata in proportion to population of the stratum. All the stratum-level allocations were adjusted to multiple of 2. Stratum-level sample size in the urban sector was further allocated to 2 sub-strata in proportion to the number of UFS blocks in them with double weightage to sub-stratum 1 subject to a minimum sample size of 2 or 4 to sub-stratum 1 according as stratum-level allocation is 4 or greater than 4. Sub-stratum level allocations in the urban sector were made even.
Selection of FSUs:
FSUs were selected in the form of two independent sub-samples in both the sectors. For special stratum 2 and all the general strata of rural sector, FSUs were selected by probability proportional to size with replacement (PPSWR) where size was the 1991 census population. For urban sector and special stratum 1 of rural sector, FSUs were selected by simple random sampling without replacement (SRSWOR).
Selection of hamlet-groups/sub-blocks / households
Formation of hamlet-group/sub-block:
Large villages/ blocks having approximate present population 1200 or more were divided into a suitable number of hamlet-groups/sub-blocks.
less than 1200 1 (no hamlet-group/sub-block formation)
1200 to 1799 3
1800 to 2399 4
2400 to 2999 5
3000 to 3599 6
....and so on
For rural areas of Himachal Pradesh, Sikkim and Poonch, Rajouri, Udhampur and Doda districts of Jammu and Kashmir and Idukki district of Kerala where habitation pattern causes difficulty in listing due to topography of the area, hg formation criterion was relaxed for which number of hamlet groups formed as per population criterion is given below:
less than 600 1 (no hamlet-group/sub-block formation)
600 to 899 3
900 to 1199 4
1200 to 1499 5
....and so on
Hamlet-groups / sub-blocks were formed by more or less equalising population. For large urban blocks, the sub-block (sb) having slum dwellers, if any, was selected with probability 1 and was termed as segment 1.
However, if there were more than one sb having slum dwellers, the sb having maximum number of slum dwellers was selected as segment 1. After selection of sb for segment 1, one more sb was selected by simple random sampling (SRS) from the remaining sb's of the block and was termed as segment 2.
For large blocks (having no slum areas) two sub-blocks were selected by simple random sampling without replacement (SRSWOR) and were combined to form segment.
For urban blocks without sub-block formation, segment number was 1 or 2 depending on whether the block was having a slum or not. For large villages two hamlet-groups were selected by SRSWOR and were combined to form segment 2. For villages without hamlet-group formation, segment number was also 2. The segments were considered separately for listing and selection of the ultimate-stage units.
Formation of Second Stage Strata (SSS) and selection of households for schedules 1.2 and 1.0: In each selected village/block/segment, three and two second stage strata (SSS) were formed for schedule 1.2 and schedule 1.0 respectively on the basis of structure type in rural areas and household MPCE in urban areas.
Data collection

| 2002-07 | 2002-12 |
The survey period of this round was divided into two sub-rounds of three months duration each as follows:
Sub-round 1: July-September 2002
Sub-round 2: October-December 2002
As far as possible, equal number of sample FSUs was allotted for survey in each of the two sub-rounds to ensure uniform spread of sample FSUs over the entire round. Attempt was made to cover each such FSU during the sub-round to which was allotted. Because of the arduous field conditions, this sub-round restriction was relaxed in Andaman and Nicobar Islands, Lakshadweep, rural areas of Arunachal Pradesh and Nagaland.
