Socio-Economic/Monitoring Survey [hh/sems]
The 50th round of NSS was the NSS Organisation's fifth quinquennial survey on consumer expenditure and employment-unemployment. According to a decision of the Governing Council of NSSO, consumer expenditure and employment surveys are carried out simultaneously every five years. The previous four rounds quinquennial surveys were the 27th (Oct. 1972 - Sept. 1973), the 32nd (July 1977 - June 1978), the 38th (Jan-Dec. 1983), and the 43rd (July 1987- June 1988). In other rounds of NSS, too, a consumer expenditure inquiry on a reduced scale is being carried out from the 42nd round (1986-87) onwards. From the 45th round onwards the subject coverage of this schedule has been expanded to include some important questions on employment so that an annual series of consumer expenditure and employment data is now available. While some of these smaller-scale surveys are spread over a full year and others over six months only, the quinquennial (full-scale) surveys have all been of a full year's duration.
In the quinquennial surveys two separate schedules are canvassed - sch.1.0 for consumer expenditure and sch.10 for employment situation - in each sample household, enabling cross- tabulation of consumer expenditure and employment data.
Schedule 1.0 primarily collects information on consumer expenditure data, along with some information on demographic particulars and household characteristics. A special feature of the consumer expenditure schedule used in the quinquennial rounds is the provision for simultaneous collection of data on consumption for a month and a year for certain items whose consumption at the household level does not have a monthly regularity, e.g. durable goods, clothing and footwear.
The survey period of the 50th round was from July 1993 to June 1994. The survey period of one year was divided into four sub- rounds of three months each and equal numbers of sample villages and blocks allotted to each sub-round.
Following usual NSS practice, the sample of villages and blocks in which the enquiry was carried out was drawn in the form of two independent sub-samples. Either of these sub-samples could be used to generate a valid set of estimates which might be regarded as the provisional results of the survey until such time as the final results, based on the entire sample, were available.
Using this data one can find out household consumer expenditure at state and all-India level, distributions of households and persons by value of monthly per capita consumer expenditure, averages (state and all-India) of monthly per capita consumer expenditure, the break-up of these average values by important heads of consumption, break-ups of quantity and value of per capita cereal consumption by cereal type (rice, wheat, etc.) etc. separately for rural and urban sectors. The schedule also collected some other household particulars including age, sex and educational level etc. of each household member.
The National Sample Survey Organisation (NSSO) has been carrying out All-India surveys quinquennially on consumer expenditure and employment - unemployment. The 50th round (July 1993 - June 1994) was the Fifth quinquennial survey on Consumer Expenditure and Employment - Unemployment. The previous four quinquennial surveys were the 27th (Oct. 1972 - Sept. 1973), the 32nd (Jul.1977 - Jun. 1978), the 38th ( Jan. - Dec. 1983) and 43rd (Jul. 1987 - Jun. 1988) rounds. In other rounds of NSS, also, a consumer expenditure inquiry on a limited scale was being carried out from the 42nd round (1986-87) onwards. From the 45th round onwards the subject coverage of this schedule has been expanded to include some important questions on employment so that an annual series of consumer expenditure and employment data is now available. While some of these smaller-scale surveys are spread over a full year and others over six months only, the quinquennial (full-scale) surveys have all been of a full year's duration. Household consumer expenditure is measured as the expenditure incurred by a household on domestic account during a specified period, called reference period. It includes the imputed values of goods and services, which are not purchased but procured otherwise for consumption. In other words, it is the sum total of monetary values of all the items (i.e. goods and services) consumed by the household on domestic account during the reference period. The imputed rent of owner-occupied houses is excluded from consumption expenditure. Any expenditure incurred towards the productive enterprises of the households is also excluded from household consumer expenditure. The household consumer expenditure schedule used for the survey collected information on quantity and value of household consumption with a reference period of "last 30 days" for some items of consumption and "last 365 days" for some less frequently purchased items. To minimise recall errors, a very detailed item classification was, as usual, adopted to collect information, including 148 items of food, 13 items of fuel, 28 items of clothing, bedding and footwear, 18 items of educational and medical expenses, 52 items of durable goods, and about 85 other items. The schedule also collected some other household particulars including age, sex and educational level etc. of each household member.
The schedule design for the survey was more or less similar to that adopted in the previous quinquennial round. The field work for the survey was conducted, as usual, by the Field Operations Division of the Organisation. The collected data were processed by the Data Processing Division of NSSO and tabulated by the Computer Centre of Department of Statistics. The reports have been prepared by Survey Design & Research Division (SDRD) of NSSO under the guidance of the Governing Council, NSSO.

Scope
The NSSO surveys on consumer expenditure aim to measure the household consumer expenditure in quantitative terms disaggregated by various household characteristics .
The data for this survey was collected in the NSS Schedule 1.0 used for household consumer expenditure. For this round, the schedule had 14 blocks.
Blocks 0, 1 and 2 - were similar to the ones used in usual NSS rounds. These were used to record identification of sample households and particulars of field operations.
Block-3: Household characteristics like, household size, principal industry-occupation, social group, land possessed and cultivated, use of hired labour, monthly per capita expenditure etc. were recorded in this block.
Block-4: In this Block the detailed demographic particulars including age, sex, educational level, marital status, number of meals usually taken in a day etc. were recorded. Besides this, information on consumption of tobacco was also recorded in this block.
Block-5: In this block cash purchase and consumption of food, pan, tobacco, intoxicants and fuel and light during the last 30 days were recorded.
Block-6: Block 6 was used to record the information of cash purchase and consumption of clothing during the last 30 and 365 days.
Block-7 : Further probing questions on the cash purchase and consumption of footwear during the last 30 and 365 days were made in this block.
Block-8: - Expenditure (cash and kind) on the miscellaneous goods and services and rents & taxes during the last 30 days and expenditure (cash & kind) on educational and medical goods and services during the last 30 days and 365 days were recorded in blocks 8 and 8.1 respectively.
Block-9: In Block 9, questions were asked about expenditure (cash and kind) for the purchase and construction (including repair) of durable goods for domestic use during the last 30 and 365 days.
Block-10: Block 10 was canvassed to record the perception of household regarding sufficiency of food.
Block 11 - In this block insurance particulars of the household during the last 365 days were recorded.
Block 12 - In this block particulars of dwelling unit were recorded.
Block 13 - In this block particulars of ceremonies performed and meals served by the household during the last 30 and 365 days were recorded.
Block 14 - Contains the summary of consumer expenditure during the last 30 days.
Coverage
The survey period of the 50th round was from July 1993 to June 1994. The geographical coverage of the survey was to be the whole of the Indian Union except Ladakh and Kargil districts of Jammu & Kashmir, 768 interior villages of Nagaland and 172 villages in Andaman & Nicobar Islands which remain inaccessible throughout the year. However, certain districts of Jammu & Kashmir viz., Doda, Anantnag, Pulwama, Srinagar, Badgam, Baramula and Kupwara, and Punjab's Amritsar district, had to be excluded from the survey due to unfavourable field conditions.
The survey used the interview method of data collection from a sample of randomly selected households and members of the household.

Sampling
The sample design adopted for this round of survey was similar to that followed in the past surveys in its general aspects. The general scheme was a two stage stratified design with the first stage units being villages in the rural areas and urban frame survey blocks (UFS) in the urban areas. The second stage units were the households.
Sampling frame for first stage units:
The latest available lists of census villages (which are mostly the 1981 census lists) constitute the sampling frame for the rural sector. For Nagaland, the villages located within 5kms of a bus route constitute the sampling frame whereas, for Andaman & Nicobar Islands, the list of accessible villages constituted the sampling frame. For the urban sector, the lists of NSSO Urban Frame Survey (UFS) blocks have been considered as the sampling frame. However, for some of the newly declared towns of 1991 census for which UFS frame has not been received, the lists of 1991 census EBs have been considered as the sampling frame.
Region formation and stratification:
States were divided into regions by grouping contiguous districts similar in respect of population density and cropping pattern. In rural sector each district was treated a separate stratum if the population was below 2 million and where it exceeded 2 million, it was split into two or more strata. This cut off point of population was taken as 1.8 million ( in place of 2 million ) for the purpose of stratification for districts for which the 1981 census frame was used. In the urban sector, strata were formed, within each NSS region on the basis of population size class of towns. However, for towns with population of 4 lakhs or more the urban blocks were divided into two classes viz. one consisting of blocks inhabited by affluent section of the population and the other consisting of the remaining blocks.
Selection of first stage units :
Selection of sample villages was done circular systematically with probability proportional to population and sample blocks circular systematically with equal probability. Both the sample villages and the sample blocks were selected in the form of two or more independent sub-samples. In Arunachal Pradesh the procedure of cluster sampling has been followed. Further large villages/blocks having present population of 1200 or more were divided into a suitable number of hamlet- groups/ sub-blocks having equal population content. Two hamlet- groups were selected from the larger villages while one sub-block was selected in urban sector for larger blocks.
Selection of households :
While listing the households in the selected villages, certain relatively affluent households were identified and considered as second stage stratum 1 and the rest as second stage stratum 2.
A total of 10 households were surveyed from the selected village/hamlet-groups, 2 from the first category and remaining from the second.Further in the second stage stratum-2, the households were arranged according to the means of livelihood. The means of livelihood were identified on the basis of the major source of income as i) self-employed in non-agriculture, ii) rural labour and iii) others. The land possessed by the households was also ascertained and the frame for selection was arranged on the basis of this information. The households were selected circular systematically from both the second stage strata.
In the urban blocks a different method was used for arranging the households for selection. This involved the identification means of livelihood of households as any one of a) self-employed, b) regular salaried/wage earnings, c) casual labour, d) others. Further the average household monthly per capita consumer expenditure (mpce) was also ascertained. All households with MPCE of (i) Rs. 1200/- or more (in towns with population less than 10 lakhs or (ii) Rs. 1500/- or more (in towns with population 10 lakh or more) formed second-stage stratum 1 and the rest, second-stage stratum 2.The households of second-stage stratum 2 were arranged according to means of livelihood class and MPCE ranges before selection of sample households. A total of 10 households were selected from each sample block as follows
(i) For affluent strata/classes : 4 households from second- stage stratum 1 and 6 households from second-stage stratum 2
(ii) For other strata/classes : 2 households from second-stage stratum 1 and 8 from second-stage stratum 2.
Households were then selected circular systematically with a random start.
Shortfall in the required number of household in any second-stage stratum was made up by increasing the quota for the other second stage stratum.
A total of 7284 sample villages (Rural) and 4792 sample blocks (Urban) were allotted in central sample. 6983 sample villages and 470 sample blocks were successfully surveyed covering 356351 persons in sample villages and 208389 persons in sample blocks.
There was no deviation from the original sampling design.
Two different weights have been provided in each file in the data set. Details are as follows:-
- Weight for each sub sample is stored in the variable name : MLT_subsample
- Combined subsample weight is stored in the variable name : MLT_combined
