Final Multiplier-posted unit-level data for schdules 1.0 of NSS 63nd round. A)Data for Household Consumer Survey (Sch. 1. 0). Data Files -------------------------------------------------------------------------------------- No. of No. of Data records bytes File name (uncompressed) -------------------------------------------------------------------------------------- 767831 109799833 data1.txt for states with codes = 09,11,12,13,15 860422 123040346 data2.txt for states with codes = 10,14,16,18,21(R) 806317 115303331 data3.txt for states with codes = 17,19,21(U),35 778109 111269587 data4.txt for states with codes = 01,02,03,04,06,07 2046048 292584864 data5.txt for states with codes = 05,22,23,27,28,30,31,32 127881 18286983 data6.txt for states with codes = 20 619493 88587499 data7.txt for states with codes = 08,24,25,26 942363 134757909 data8.txt for states with codes = 29,33,34 -------------------------------------------------------------------------------------- Record length for data is 142 for all types of schedules. B) Multiplier files ------------------------------------- for schdules 1.0 ------------------------------------- No. of No. of Data records bytes File name (uncompressed) ------------------------------------- 13322 2824264 mlt63.txt Record length is 211 (Multipliers are already posted onto data files.) 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 layout_63_1.0.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 layout_63_1.0.xls. (4) For generating any estimate, one has to extract relevant portion of the data, and aggregate after applying the weights. (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 : 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 household will have same weight figure. In case of those Blocks/Levels, where Item/Person Sl.No. is not applicable the field is filled up with 00000. (6) 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. ----------------------------------------------------------------------------- (7) 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) Household Serial Number = 35(2) Level Number = 37(2) Item/ Person Serial Number = 39(5) ------------------------------------------------------------------------------- (8) List of Documents ------------------ General Information - README63.TXT Text Data Layout - Layout_63_1.0.xls Subsample-wise multiplier file layout for schedules 1.0 - Layout_mult_63_1.0.doc Instruction to Field Staff - Instrn. to Field Staff_63 Estimation procedure note and related tables for 63nd round - Estimation Procedure_63.doc State codes - State Codes_63.doc ------------------------------------------------------------------------------ Note : (1) f.s.u. serial numbers in records are assigned false numbers to disable identity of units; (2) files are in ASCII format and they are flat / line sequential.
