But statistics on the unorganised part of this sector are not available regularly in usable form. To bridge the gap, a countrywide census  of all non-agricultural units employing at least one hired worker was undertaken in 1977 by the CSO in collaboration with the State Statistical Bureaus.  This census \nprovided a list of all establishments (units having at least one hired worker) in the unorganised sector of economic activities.  Using the frame provided by the Economic Census, a follow-up survey of small trading establishments employing five or fewer number of workers and relatively smaller trading units not employing any hired worker was conducted in the thirty-fourth round of the NSS in 1979-80. \n\nThe second Economic Census was conducted in 1980. It had a wider coverage than the earlier one in the sense that it covered the own-account enterprises (units without any hired worker are called Own-Account Enterprises or OAEs) also.  In this census the establishments were further split into two categories :  Directory Establishments (DEs) and Non-Directory Establishments (NDEs); \nthe former employed a total of six or more  workers, while the l atter employed a total of five or fewer workers.  Thus, the second Economic Census dealt with three categories of units, viz. DEs, NDEs and OAEs.  This census provided a list of villages \/ enumeration blocks (EBs) giving a count of enterprises and establishments, which has been used by the NSSO as a frame for sample villages \/ EBs in its follow-up surveys.  Two such surveys of units engaged in trading activities were taken up by the NSSO in its forty-first round (July 1985 to June 1986) and forty-sixth round (July 1990 to June 1991).   \n\nThe third Economic Census was conducted in the year 1990. The coverage and the classification of the enterprises were the same as those of the second Economic Census. Using the frame based on the third Economic Census, a similar survey on the small trading units was undertaken by the NSSO in its fifty-third round during January to December, 1997.  \n\nIn this round, the usual practice of hamlet group \/ sub-block formation was dispensed with. Instead, the whole fsu's (i.e. villages \/ blocks) were listed as first stage units. As a result, the workload increased manifold in the field. In a later decision of the Governing Council,  a portion of the   samples was curtailed from the original allocation. It was also decided that the villages with population 20,000 or more as per 1991 census  omitted from the sample. \n\nAll the second-stage units (i.e. trading enterprises) were listed through a listing schedule. This list constituted the frame for drawing the required number of sample enterprises from each first -stage unit. The enterprises were divided into three  enterprise classes on the basis of the number of workers  employed, from each of which a certain specified number of enterprises were selected. Information collected through the listing schedule was used for calculating multipliers and for estimation o f the number of enterprises. The enterprise schedule was canvassed in the selected sample enterprises for collecting information on basic items like  fixed assets, employment, purchase and sale values, other expenditure, value added and trade margins of commodities traded. Enterprises were selected in this round from three enterprise classes. The main characteristics on which information were collected are fixed assets, employment, purchase and sale values, other expenditure, other receipts, value added and trade margin of the traded goods. Reference period for collection of data was 'month' except for fixed assets and trade margin, where the reference period used was 'last one year'.\n\nA maximum of 16 enterprises (OATEs and NDTEs only for schedule 2.41.2) were surveyed.The schedule 2.41.2 consisted of 10 blocks. \n\nAll the enterprises covered by the two-digit codes (called divisions) 60 to 68 and three-digit codes (called groups) 040, 052, 053, 054, 059, 060, 061, 063, 069 and 890 under the revised National Industrial Classification, 1987 (NIC, 1987) were considered for this survey. Strictly speaking, the activity codes 040,052,..,069, which represent various free collection activities for sale, should be covered under agriculture. But value added for such activities were not regularly available from official sources. As such, they were  covered under unorganised trade since the NSS 34th round. \n\nImportant concepts and definitions followed in the survey of NSS 53rd round were :-\n\nTrade : Trading is defined as an act of purchase of goods and their disposal by way of sale without any intermediate physical transformation of goods. The activities of intermediaries who do not actually purchase or sell the goods but arrange their pur\u00adchase and sale and thereby earn  remuneration by way of brokerage or commission, are also covered for the purpose of `trade` sur\u00advey. Distributive agencies which undertake trading activity on  commission basis are also included. In addition, the activities of free collection for sale of honey and forest products like gathering of fodder, grass, etc.; free hunting, trapping and game propagation for commercial purposes; free collection for sale of fish, prawns, crabs and oysters; free collection for sale of waste paper, ash, rags, coal, etc., are also treated as trade for this survey. Separate and distinct trading units of manufacturing concerns like sale shops of Delhi Cotton Mill, Bombay Dyeing, Bata Shoe, etc., and activities like selling of fruit juice, sugar\u00adcane juice, etc. which involve a process of transformation mar\u00adginally are also covered under trade. \n\nTrading enterprise: A trading enterprise is an undertaking\/unit engaged in trade. An enterprise may be owned and operated by a household  or by an institutional body. The activi\u00adties of the enterprise may be carried on by household members and\/or by hiring outside labour.\n\nOwn-account enterprise:  An enterprise which is run by house\u00adhold workers only (i.e. without any hired worker on a fairly regular basis ) is termed as an own-account enterprise. If such an enterprise is engaged in trading, it is termed as an own-account trading enterprise (OATE). \n\nEstablishment: An enterprise which is employing at least one hired worker on a fairly regular basis is termed as an establishment.\n\nNon-directory establishment : An establishment employing fewer than six workers (household and hired workers taken togeth\u00ader) is termed as a non-directory establishment. If such an estab\u00adlishment is engaged in trading activities, it is termed as a non-directory trading establishment (NDTE).\n\nReference period :  It means the period for which informa\u00adtion on a particular characteristic is collected. In the NSS 53rd round only one reference period, viz. 'month' was used to collect the data. However, data on trade margins and net addi\u00adtions to fixed assets were collected for the last one year.\n\n\nIdentification particulars of sample enterprise were recorded in Blocks 0 and 1.\nBlock 0 contained items on which descriptive identification of sample enterprise were written whereas Block 1 was meant for coded identification particulars of the sample enterprise. Particulars of operation and some background imformation about the sample enterprise were collected in Block 2. \nBlocks 3  was meant for for collecting information on employment particulars. \nAccount of commodities purchased and sold during the month weree recorded for 73 specified commodity groups through Block 4. Block 5 recorded the expenditures of the enterprise excluding the commodities purchased. Surplus or profit of the enterprise were also be collected in Block 5. \n\nFor the first time, in Block 6  Gross Value Added during the reference month were calculated in the schedule itself in this round. \nIn Block-7 recorded the trade margins for the same set of 73 commodity groups specified in Block 4.\n\nParticulars of Field Operations were recorded in Block 8, whereas in Blocks 9 and 10 recorded  the remarks by the investigator and comments by the supervisory  officers."},"method":{"data_collection":{"data_collectors":[{"name":"Field Operations Division of Naional Sample Survey Office","abbr":"NSSO(FOD)","role":"","affiliation":"Ministry of Statistics and Programme Implementation "}],"sampling_procedure":"A stratified two-stage sampling design was adopted for the survey. The first stage units (FSUs) were the villages (panchayat wards  in case of Kerala) in the rural sector and UFS blocks in the urban sector. The second-stage units were the OATEs and NDTEs for the trade survey. \nThe total all -India sample size of FSUs was  allocated to different States\/U.Ts in proportion to the number of workers engaged in OATEs\/NDTEs in the respective States\/U.Ts ( estimated as number of OATE\/NDTE as per EC '90 multiplied by estimated number of workers per enterprise based on NSS 46th round) subject to a minimum allocation given to the State\/U.Ts depending upon the total number of  districts and town classes for the State\/U.T. The State\/U.T level sample size was again allocated to the rural and urban sectors in proportion  to the number of workers. \n\nRural sector design  \n \nSampling frame   :  The list of villages showing number of  OATEs and NDTEs as per 1990 Economic Census was used for selection of villages in the States\/U.Ts wherever such frame was available. For Kerala, list of Panchayat wards giving count of OATEs \/NDTEs has been used as the frame for selecting Panchayat wards f or the the survey instead of villages. For Jammu & Kashmir, the \n1981 census lists of villages forms the frame. For Andaman & Nicober islands, Lakshadweep and 5 districts of Madhya Pradesh, 1991 census lists were used as frame. For Andaman & Nicober Islands, villages remaining inaccessible throughout the year were excluded from the frame. For Nagaland, onlyvillages connected by bus or situated within 5 kms of the bus route were included in the frame. \n \nStratification   :  Each district generally formed a broad stratum. However, for Gujarat, where NSS regions cut across district boundaries, parts of each such part of a district formed a separate stratum. If any district (or part thereof lying in an NSS region in case of Gujarat) had a small number of trading enterprises, it was clubbed with a neighbouring district to form a broad  stratum in order to ensure a minimum allocation. To net an adequate number of NDTEs in the sample, each broad stratum was divided into two area types : (i)  Area type 1 consisting of villages having at least one  NDTE, and  (ii)  Area type 2 consisting of the remaining villages of the  broad stratum.  \n \nWhere population census frames were used for selection of fsus , there was no division as above.  In such cases, all the villages  were classified in area type 2. \n\nAllocation of sample villages among strata and area types  :    The State\/U.T  level rural sample size was allocated among the strata in proportion to number of workers.  While allocating as above, it was maintained that NSS region level allocation were multiples of 8 and stratum level allocation is at least 4 but in multiples of 2.  This was done in order to allocate at least two fsu's to each \nof the area types.  The stratum level allocation was again di stributed between two area types in proportion to number of NDTEs and OATEs taking into consideration that allocation for each area type was in multiples of 2. \n \nSelection of fsu's  :   Villages were selected in the form of two independent sub-sampl es from each broad  stratum  X area type using circular systematic sampling with probability proportional to size, the size being the number of (OATE + NDTE) for area type 1 and the number of OATEs ( after assigning a size of 1 to the fsu's having no tradi ng enterprise) for area type 2. \n \nWhere population census frame was used, villages were selected using circular systematic sampling with probability proportional to population. For Lakshadweep and A & N Islands, however, equal probability sampling was adopted. \n \n Urban sector design  :    \n \nSampling  Frame   :   The latest available list of UFS blocks was  used as sampling frame for selection of fsu's for all cities and towns. \n \n Stratification  :   Town classes (broad strata) were formed within each district by grouping cities\/towns according to population sizes as per '91 census. To net adequate number of trading enterprises in the sample, each town class was divided into two area types.  Area type 1 consisted of the UFS blocks  designated as 'bazar area' and area type 2 consisting of the remaining blocks of the town class. \n \nAllocation of sample blocks among districts, town classes and area types :   The state\/u..t. level urban allocation is allocated among the districts and town classes in proportion of the number of workers.  It is, however, ensured that NSS region level allocations were in multiples of 8 and town class level allocations were at least 4 and were in multiples of 2.  Town class level allocations were further \nallocated between two area types in such a way that UFS blocks of area type 1 get completely surveyed (central and state samples combined) subject to a maximum of 50% of allocation for town class level. Area type wise allocations were in multiples of 2.  \n \nSelection of blocks : For both the area types, sample blocks were selected circular systematically in the form of two independent sub-samples with equal probability. \n \n Sampling of enterprises   :  All the OATEs and NDTEs of the selected village\/block excluding those in the public sector and which operated for at least 30 days (15 days in case of seasonal enterprises) during the last 365 days preceding the date of survey were considered for sampling. All such, eligible enterprises were classified into three classes termed as  'enterprise class' according to \nthe total number of workers (including hired workers) employed in the enterprises on a regular basis. \nThe classes were as follows : \n\n \n                      ---------- ------------------------------------------------------------------------ \n                         Enterprise                       Composition of the class \n                         class code \n                      ------------------------------------------ ---------------------------------------- \n \n                              1                all OATEs and NDTEs with one worker only. \n \n                              2                all OATEs and NDTEs with two workers only. \n \n                              3                all OATEs and NDTEs with three or more workers. \n                      ----------------------------------------------------------------------------------- \n \nBefore selecting enterprises from enterprise classes, all the enterprises within an enterprise class were arranged in ascending order of their NIC codes. The number of enterprises  selected from enterprise classes 1, 2 and 3 were 4, 6 and 6 respectively. If there is a shortfall in enterprise class 3, it is made up from enterprise class 2, if possible, otherwise from enterprise class 1. Similarly, if there is a shortfall in enterprise class 2, it is made up from enterprise class 3, failing which from enterprise class 1. The priority order for compensation is 3rd, 2nd and 1st enterprise class.  \n \nThe required number of enterprises were selected from each enterprise class circular systematically with equal probability.","sampling_deviation":"There was no deviation from the original sampling design","coll_mode":["Face-to-face [f2f]"],"research_instrument":"The schedule 2.41.2 consists of 10 blocks as given below,\n\nBlock 0 : Descriptive identification of sample enterprise \nBlock 1 : Identification of sample enterprise\nBlock 2 : Particulars of  operation and background infor\u00admation      \nBlock 3 : Employment particulars during reference month  \nBlock 4:  Account of commodities purchased and sold\nBlock 5: Expenditure of the enterprise during reference month\nBlock 6: Calculation of gross value added during reference month\nBlock 7: Trade Margin for different commodities traded\nBlock 8 The particulars of field operation.\nBlocks 9 and 10:Remarks by the investigator and comments by the supervisory officers.","sources":[{"name":"","origin":"","characteristics":""}],"coll_situation":"The survey period of one year duration, starting from 1st January 1997 & ending on 31st December 1997, was divided into four parts called sub-rounds.
