Phone No. (033) 2577-1128. --------------------------------------- NSS 61st Round. Final Multiplier-posted unit-level data of Employment-Unemployment Survey (Sch.10). Data Files ----------------------------------------------------------------------------------- No. of No. of Data Remarks records bytes File name ----------------------------------------------------------------------------------- 864380 132250140 ah12.txt for states with codes = 9,11,13,15,17 737821 112886613 ah22.txt for states with codes = 10,14,16,18 713935 109232055 ah32.txt for states with codes = 12,19,21,35 680106 104056218 ah42.txt for states with codes = 01,02,03,04,06,07 1642778 251345187 ah52.txt for states with codes = 05,22,23,27,28,30,31,32 161385 24691905 ah62.txt for states with codes = 20 481416 73656648 ah72.txt for states with codes = 08,24,25,26 619477 94779981 ah82.txt for states with codes = 29,33,34 ----------------------------------------------------------------------------------- Multiplier files ------------------------------------- 12788 3874764 multalls2.61 12788 3874768 mltsubs10.all ------------------------------------- Record length is 302 for both the multiplier files. (The Multipliers / Weights are already posted onto data files.) Note for users : ---------------- (1) These are text data with fixed record-length of 152 characters. First 126 bytes are data, and remaining 26 bytes are weights. (2) The Layout of data is given in the EXCEL-file layout.xls. (3) The data is organized 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.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. In each record, there are two sets of weights (multipliers) - the first set is "Subsample-wise sampling design based multiplier" and the second set is "post-survey adjusted sub-round-wise subsample combined multiplier" as given below:(For description of subsample and sub-round please see Instructions Manual for field staff, Vol.-I) "sub-sample-wise design based weights" ---------------------------------------- NSS = Bytes 127-129 (3 bytes) NSC = Bytes 130-132 (3 bytes) MLT_SS = Bytes 133-142 (10 bytes) ----------------------------------------- "sub-round wise subsample combined weights" -------------------------------------------- MLT_SR = Bytes 143-152 (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. (7) In the value fields (Rs. or Quantity or Area etc.) only the numeric figure is given in data-file. 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 sub-rounds taken together, either Subsample-1 households or Subsample-2 households 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: weight = MLT_SS/100 For generating subsample-combined estimates based on data of all subrounds taken together all households are to be considered. Apply weight (or multipliers) as follows: weight = MLT_SS/100, if NSS=NSC = MLT_SS/200 otherwise -------------------------------------------------------------------------- Use of "sub-round wise subsample combined weights" (multipliers) -------------------------------------------------------------------------- For generating sub-round-wise subsample combined estimates, either all Sub-round-1 households or all Sub-round-2 households or all Sub-round-3 households or all Sub-round-4 households are to be considered at one time. Sub-round code is available in the data file. (Please see layout of data). rs are to be used. Apply the sub-round wise subsample combined multiplies (or weights) as follows: weight = MLT_SR/100 ----------------------------------------------------------------------------- (8) Common Primary Key for identification of a record for any record is FSU Serial Number = 4(5) (i.e., offset = 4th byte, length = 5 bytes) Hamlet-Group /Sub-Block Number = 31(1) Second Stage Stratum Number = 32(1) Household Serial Number = 33(2) Level Number = 35(2) Item/ Person Serial Number = 37(5) ------------------------------------------------------------------------------ List of Documents ------------------ General Information - README.TXT Text Data Layout - Layout.xls Subsample-wise multiplier file layout - mltlay61.doc Sub-round wise subsample combined multiplier file layout - srmltlay61.doc Instructions for Schedule 10 Chapter 1 of Instructions Vol. I - Chapter-1.doc Chapter 2 of Instructions Vol. I - Chapter-2.doc Chapter 4 of Instructions Vol. I - Chapter-4.doc Blank Schedule 10 - 61sch10.doc Estimation procedure for 61st round Estimation_procedure.doc State codes - State code.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.
