Abstract

The National Sample Survey Organisation (NSSO) carried out the first country wide comprehensive survey of physically disabled persons during the 36th round survey (July - December, 1981). The next survey on the subject was carried out after a period of ten years in NSS 47th round (July - December, 1991). In NSS 36th and 47th round surveys, information was collected on three types of physical disabilities - visual, communication and locomotor - along with the cause of disability, aid/appliance acquired by the disabled, general and vocational educational level of the disabled etc. In addition, data on developmental milestones and behavioural pattern of all children of age 5-14 years, regardless of whether they were physically disabled or not, were collected.

The Ministry of Social Justice and Empowerment (MSJE) made a request for conducting a survey on disability in order to meet the data needs for evolving specific strategies and interventions during the 10th Five Year Plan. The need for a detailed survey on disability was strongly felt by MSJE since its data requirement included not only the number of disabled persons, but also the socio-economic characteristics of the disabled persons such as their age structure, literacy, vocational training, employment, causative factors of disability, age at the onset of disability etc. Keeping in view the urgent data need of the MSJE, the Governing Council of NSSO, in its 81st meeting, decided that the survey on disability may also be carried out as a part of NSS 58th round during July - December 2002. It has been decided that: (i) The survey of disabled persons will also cover persons with mental disability apart from the physically disabled persons since the Ministry of Social Justice and Empowerment (MSJE) also requested for information on mentally disabled persons. The decision to include mental disability in the survey has been taken on the basis of a pre-test of the questions on mental disability, both for the listing and detailed schedules, carried out in the four cities of Kolkata, Mumbai, Hyderabad and Delhi.

(ii) The information for different types of disabilities is to be collected for persons of all age-groups. Separate information on the developmental milestones of children will not be collected.

Geographic coverage

The survey covered the whole of the Indian Union except (i) Leh 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.

Sampling procedure

Sample Design

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. The ultimate stage units were households in both the sectors.

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 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
The stratum numbers was retained as above even if, in some regions, some of the stratum is not formed.

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 as given below: approximate present population no. of hamlet-groups/ sub-blocks formed
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: approximate present population no. of hamlet-groups/ sub-blocks formed
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 2. 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 schedule 26

In each selected village/block/segment, three second stage strata (SSS) were formed on the basis of disability type. The number of households selected is given below: Without segment formation with segment formation (for each segment)

Abstract

The surveys on 'Household Social Consumption: Education' conducted by NSSO covers both qualitative and quantitative aspects related to educational attainment of the household members and educational services used by them. Qualitative aspects include literacy, educational level attained, type of institution, current attendance/enrolment, whether received free education, reason for 'never enrolled'/'ever enrolled but currently not attending', etc. On quantitative aspects, information was collected on 'expenditure incurred/to be incurred on education' of the household member by the household itself, by other households or by any institutions/organizations other than Government.

Reference period : July 2017-June 2018

Period of survey and work programme: The survey period of the round will be divided into four sub-rounds of three months’ duration each as follows: sub-round 1 : July - September 2017 sub-round 2 : October - December 2017 sub-round 3 : January - March 2018 sub-round 4 : April - June 2018

Objective of Survey on 'Household Social Consumption: Education' (Schedule 25.2): The main objective of the survey on “Household Social Consumption: Education” conducted by NSSO is to build indicators on participation of the persons in the education system, expenditure incurred on education of the household members and on various aspects of those currently not attending education (i.e., for the persons who never enrolled or who ever enrolled but currently not attending education). The surveys on ‘Household Social Consumption: Education’ conducted by NSSO covers both qualitative and quantitative aspects related to educational attainment of the household members and educational services used by them. Qualitative aspects include literacy, educational level attained, type of institution, nature of institution, current attendance/enrolment, whether received free education, reason for never enrolled/ever enrolled but currently not attending, etc. On quantitative aspects, information is collected on expenditure incurred/to be incurred on education of the household member by the household itself, by other households or by any institutions/organizations other than Government.

Universe

The survey used the interview method of data collection from a sample of randomly selected households and members of the household.

Sampling procedure

Sample Design 3.1 Outline of sample design: A stratified multi-stage design has been adopted for the 75th round survey. The first stage units (FSU) are the Census villages (Panchayat wards for Kerala) in the rural sector and Urban Frame Survey (UFS) blocks in the urban sector. The ultimate stage units (USU) are households in both the sectors. In the case of large FSUs, one intermediate stage of sampling is the selection of two hamlet-groups (hgs)/ sub-blocks (sbs) from each rural/ urban FSU. 3.2 Sampling Frame for First Stage Units: For the rural sector, the list of 2011 Population Census villages constitutes the sampling frame. However, for Kerala, the latest available updated list of Panchayat wards constitutes the sampling frame. For the urban sector, the latest available list of UFS blocks has been considered as the sampling frame. 3.3 Stratification: (a) Each district is a stratum. Within each district of a State/UT, generally speaking, two basic strata have been 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 are one or more towns with population one million or more as per Census 2011, each of them formed as a separate basic stratum and the remaining urban areas of the district have been considered as another basic stratum. (b) In the case of rural sectors of Nagaland another special stratum has been formed within the State consisting of all the villages which are difficult to access. 3.4 Sub-stratification: 3.4.1 Rural sector: If ‘r’ be the sample size allocated for a rural stratum, ‘r/4’ sub-strata are formed in that stratum. The villages within a stratum (district) as per frame are first arranged in ascending order of population. Then sub-strata 1 to ‘r/4’ have been demarcated in such a way that each substratum comprises a group of villages of the arranged frame and has more or less equal population. 3.4.2 Urban sector: Each urban stratum has been divided into two parts - ‘Affluent part’ consisting of UFS blocks identified as ‘Affluent Area’ and ‘Non-Affluent part’ consisting of the remaining UFS blocks within the stratum. Sample allocation of a stratum is then allocated to Affluent and Non-Affluent parts in proportion to total number of households in the UFS blocks with double weightage to Affluent part subject to a maximum of 8 FSUs in ‘Affluent part’ of any stratum. If ‘u’ be the sample size allocated for an urban stratum consisting of both affluent area UFS Blocks and non affluent area UFS Blocks. ‘u/4’ sub-strata are formed within each stratum. Out of these ‘u/4’ substrata, the first two sub-strata ‘01’ and ‘02’ are earmarked for those UFS blocks which are identified as ‘Affluent Area’ and the remaining sub-strata, ‘03’, ‘04’,…... and so on, are assigned to the nonaffluent UFS blocks. If any stratum does not have any Affluent Area UFS block then also the substratum number starts from ‘03’ for that stratum. For all strata, if u/4 >1, implying formation of 2 or more sub-strata, all the UFS blocks within the stratum are first arranged in ascending order of total number of households in the UFS Blocks as per the latest UFS phase. Then sub-strata 1 to ‘u/4’ are demarcated in such a way that each sub-stratum has more or less equal number of households. This procedure has been done separately for Affluent-part and Non-Affluent part of the stratum (if two sub-strata are required to be formed in the Affluent part). The following three cases arise while doing the sub-stratification: i) If there is no ‘Affluent Area’ UFS block in the stratum, all the UFS blocks are divided into ‘u/4’ sub-strata and numbered as ‘03’, ‘04’, ….., ‘(u/4)+2’. ii) If only one sub-stratum is formed with the ‘Affluent Area’ UFS blocks, then all the remaining non-affluent blocks are divided into ‘(u-4)/4’ sub-strata and numbered as ‘03’, ‘04’, ….., ‘(u/4)+1’. iii) If two sub-strata are formed with the ‘Affluent Area’ blocks, then all the remaining non-affluent UFS blocks are divided into ‘(u-8)/4’ sub-strata and numbered as ‘03’, ‘04’, ….., ‘u/4’. 3.5 Total sample size (FSUs): 14300 FSUs have been allocated for the central sample at all-India level. For the state sample, there are 16492 FSUs allocated for all-India. 3.6 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 population as per Census 2011 subject to a minimum sample allocation to each State/UT. 3.7 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 population as per Census 2011 with 1.5 weightage to urban sector depending on population share. A minimum of 16 FSUs (minimum 8 each for rural and urban sector separately) have been allocated to each State/ UT. 3.8 Allocation to strata: Within each sector of a State/ UT, the respective sample size has been allocated to the different strata in proportion to the population as per Census 2011. Stratum level allocation has been adjusted to multiples of 4 with a minimum sample size of 4. For special stratum formed in rural areas of Nagaland as discussed in para 3.3 (b), 12 FSUs have been allocated. 3.9 Allocation to sub-strata: Allocation for each sub-stratum has been made as 4 in both rural and urban sectors. 3.10 Selection of FSUs: 3.10.1 For the rural sector, from each stratum/sub-stratum, required number of sample villages has been selected by Probability Proportional to Size With Replacement (PPSWR), size being the population of the village as per Census 2011. 3.10.2 For the urban sector, from each stratum/sub-stratum, FSUs have been selected by Probability Proportional to Size With Replacement (PPSWR), size being the number of households of the UFS Block. Both rural and urban samples are drawn in the form of two independent sub-samples. 3.11 Selection of hamlet-groups/ sub-blocks - important steps 3.11.1 Criterion for hamlet-group/ sub-block formation: After identification of the boundaries of the FSU, it is to be determined whether listing is to be done in the whole sample FSU or not. In case the approximate present population of the selected FSU is found to be 1200 or more, it is divided into a suitable number (say, D) of ‘hamlet-groups’ in the rural sector and ‘sub-blocks’ in the urban sector by more or less equalising the population as stated below. approximate present population of the sample FSU no. of hgs/sbs formed less than 1200 (no hamlet-group/sub-block) 1 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, Andaman & Nicobar Islands, Uttarakhand (except four districts Dehradun, Nainital, Hardwar and Udham Singh Nagar), Punch, Rajouri, Udhampur, Reasi, Doda, Kishtwar, Ramban, Ladakh region (Leh and Kargil districts) of Jammu and Kashmir and Idukki district of Kerala, the number of hamlet-groups to be formed as

Sampling procedure

Outline of sample design: A stratified multi-stage design has been adopted for the 71st round survey. The first stage units (FSU) are the census villages (Panchayat wards in case of Kerala) in the rural sector and Urban Frame Survey (UFS) blocks in the urban sector. The ultimate stage units (USU) are households in both the sectors. In case of large FSUs, one intermediate stage of sampling is the selection of two hamlet-groups (hgs)/ sub-blocks (sbs) from each rural/ urban FSU.

Sampling Frame for First Stage Units: For the rural sector, the list of 2011 census villages (henceforth the term 'village' would mean Panchayat wards for Kerala) constitutes the sampling frame. In case of Kerala, due to the non-availability of Panchayat wards based on census 2011, the available list of Panchayat wards based on census 2001 is used as the rural frame. For the urban sector, the latest updated list of UFS blocks (phase 2007-12) is considered as the sampling frame.

Stratification: Stratum has been formed at district level. Within each district of a State/UT, generally speaking, two basic strata have been 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 are one or more towns with population 1 lakh or more as per Census 2011, each of them formed a separate basic stratum and the remaining urban areas of the district has been considered as another basic stratum.

Special stratum in the rural sector: There are some villages in Nagaland and Andaman & Nicobar Islands which reamins difficult to access. As in earlier rounds, a special stratum has been formed at State/UT level comprising these villages in the two State/UTs.

Sub-stratification:

Rural sector: If 'r' be the sample size allocated for a rural stratum, the number of sub-strata formed was 'r/2'. The villages within a district as per frame have been first arranged in ascending order of population. Then sub-strata 1 to 'r/2' have been demarcated in such a way that each sub-stratum comprised a group of villages of the arranged frame and had more or less equal population. Urban sector: If 'u' be the sample size allocated for an urban stratum, the number of sub-strata formed was 'u/2'. For all strata, if u/2 >1, implying formation of 2 or more sub-strata, all the UFS blocks within the stratum have been first arranged in ascending order of total number of households in the UFS Blocks as per UFS phase 2007-12. Then sub-strata 1 to 'u/2' have been demarcated in such a way that each sub-stratum had more or less equal number of households.

Total sample size (FSUs): 8300 FSUs have been allocated for the central sample at all-India level. For the state sample, there are 9274 FSUs allocated for all-India. State wise allocation of sample FSUs is given in Table 1.

Allocation of total sample to States and UTs: The total number of sample FSUs heve been allocated to the States and UTs in proportion to population as per Census 2011 subject to a minimum sample allocation to each State/ UT. While doing so, the resource availability in terms of number of field investigators has been kept in view.

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 population as per Census 2011 with double weightage to urban sector subject to the restriction that urban sample size for bigger states like Maharashtra, Tamil Nadu etc. do not exceed the rural sample size. A minimum of 16 FSUs (minimum 8 each for rural and urban sector separately) is allocated to each State/ UT.

Allocation to strata: Within each sector of a State/ UT, the respective sample size has been allocated to the different strata in proportion to the population as per Census 2011. Stratum level allocation has been adjusted to multiples of 2 with a minimum sample size of 2.

For special strata in the rural areas of Nagaland and A & N Islands, 4 FSUs has been allocated to each.

Allocation to sub-strata: Allocation for each sub-stratum has been 2 in both rural and urban sectors.

Selection of FSUs:

For the rural sector, from each stratum/sub-stratum, required number of sample villages have been selected by Probability Proportional to Size With Replacement (PPSWR), size being the population of the village as per Census 2011. For the urban sector, from each stratum/sub-stratum, FSUs have been selected by Probability Proportional to Size With Replacement (PPSWR), size being the number of households of the UFS Blocks. Both rural and urban samples have been drawn
