Government of India. Data Processing Division. National Sample Survey Division. 164, Gopal Lal Thakur Road, Kolkata-108. Phone No. 2577-1128. --------------------------------------- NSS 63rd Round. Final Multiplier-posted unit-level data for different schedules of NSS 63rd round. Data for Service Sector Enterprises (Excluding Trade) Survey (Sch. 2.345) Two types of frames were used for this manufacturing enterprises survey - area frame and list frame. So two sets of data files are provided : Data Files Data from area frame enterprises: ----------------------------------------------------------------------------------- No. of No. of File Name Remarks Records Bytes =================================================================================== 486713 69599959 ah1c23.txt for states with codes = 09,11,12,13,15 548876 78489268 ah2c23.txt for states with codes = 10,14,16,18,21(R) 636768 91057824 ah3c23.txt for states with codes = 17,19,21(U),35 530701 75890243 ah4c23.txt for states with codes = 01,02,03,04,06,07 1612675 230612525 ah5c23.txt for states with codes = 05,22,23,27,28,30,31,32 81347 11632621 ah6c23.txt for states with codes = 20 390852 55891836 ah7c23.txt for states with codes = 08,24,25,26 892503 127627929 ah8c23.txt for states with codes = 29,33,34 26094 3731442 alhcs23.txt * ------------------------------------------------------------------------------------ * Data from list frame companies /enterprises Record length for data is 142 for all types of schedules. D) Multiplier files ------------------------------------- for schedule 2.345 (area frame) ------------------------------------- No. of No. of File Name Records Bytes ===================================== 13321 6527290 mlt63.s345 ------------------------------------- Record length is 489. Note for users : ---------------- (1) These are text data with fixed record-length of 142 characters. First 126 bytes are data, and remaining 16 bytes are weights. (2) The Layout of data is given in the EXCEL-file lay63.xls. (3) The data is organised in various levels having different data formats. Information regarding which block of the Schedule has been put into which level, is given in the file lay63.xls. (4) For generating any estimate, one has to extract relevant portion of the data, and aggregate after applying the weights. It may be noted that both the list frame data and area frame data need to be considered for this purpose. (5) Weights (or multipliers) are given at the end of each record from 127th byte onwards. The weights (multipliers) are Sub-sample-wise, details of which are as given below : (For description of subsample, please see Instructions Manual for fiels staff, Vol-I) subsample-wise weights (multipliers) ---------------------------------------- NSS = Bytes 127-129 (3 bytes) NSC = Bytes 130-132 (3 bytes) MLT = Bytes 133-142 (10 bytes) ----------------------------------------- All records of a enterprise will have same weight figure. In case of those Blocks/Levels, where Item Sl.No. is not applicable the field is filled up with 00000. (6) ALL LIST FRAME ENTERPRISES HAVE EQUAL WEIGHT 1.43 (7) In the value fields (Rs. or Quantity or Area etc.) only the numeric figure is given in datafile. The decimal point is to be assumed after looking at the type of that field in the printed schedule. ---------------------------------------------------------------- Use of subsample-wise weights (multipliers) ---------------------------------------------------------------- For generating subsample-wise estimates based on data of all subrounds taken together, either Subsample-1 households /enterpeises or Subsample-2 households /enterprises are to be considered at one time. Subsample code is available in the data file. (Please see layout of data). Apply weight (or multipliers) as follows : For generating subsample-combined estimates based on data of all subrounds taken together all households/ enterprises are to be considered. Apply weight (or multipliers) as follows : weight = MLT/100, if NSS=NSC = MLT/200 otherwise. ----------------------------------------------------------------------------- (8) Common Primary Key for identification of a record for any schedule is : FSU Serial Number = 4(5) (i.e., offset = 4th byte, length = 5 bytes Hamlet-Group /Sub-Block Number = 33(1) Second Stage Stratum Number = 34(1) Enterprise Serial Number = 35(2) Level Number = 37(2) Item Serial Number = 39(5) ------------------------------------------------------------------------------- (9) List of Documents ------------------ General Information ---- README63.TXT Text Data Layout ----- Lay63.xls Subsample-wise multiplier file layout for schedule 2.345 (area frame) - mltlay63_s23.doc Instruction for Schdule 2.345 - 63ins2_345_RTC.doc Chapter 1 of Instructions Vol. I (introductory) - inschap1f.doc Chapter 2 of Instructions Vol. I (for Sch. 0.0) - inschap2f.doc Blank schedule 2.345 - sch2_345.doc Estimation procedure note and related tables for 63rd round - estpnote63.doc State codes - State code.doc Please note that Blank schedules are in the folder R63_Schedules within the common folder.
