Government of India. Data Processing Division. National Sample Survey Office. 164, Gopal Lal Thakur Road, Kolkata-108. Phone No. 2577-1128. --------------------------------------- NSS 68th Round. Final Multiplier-posted unit-level data for Schedule 10 of NSS 68th round. A) Data for Consumer Expenditure Survey (Sch. 10). There are 9 files belonging to 9 different levels as per layout (lay68_sch100.xls). Data Files -------------------------------------------------------------- No. of No. of Data records bytes # File name -------------------------------------------------------------- 101724 16174116 R6810L01.txt 101724 16174116 R6810L02.txt 456999 72662841 R6810L03.txt 456999 72662841 R6810L04.txt 38098 6057582 R6810L05.txt 495016 78707544 R6810L06.txt 172281 27392679 R6810L07.txt 99042 15747678 R6810L08.txt 2776782 441508338 R6810L09.txt -------------------------------------------------------------- 4698665 747087735 -------------------------------------------------------------- Record length for data is 158. B) Multiplier files for Schdule 10 -------------------------------------------------------------- No. of No. of Multiplier records bytes # File name -------------------------------------------------------------- 12784 2646288 mlt6810 12784 2646288 mlt6810sr -------------------------------------------------------------- Record length is 206. # : All the levelwise data files and multiplier file have been converted to DOS for user's convenience. The "No. of Bytes" shown here is according to UNIX. Note for users : ---------------- (1) These are text data with fixed record-length of 159 characters (including new-line character). First 126 bytes are data, next 6 bytes comprise of number of first stage units surveyed within a substratum for the sub-sample (NSS) and sub-sample combined (NSC) and next 10 bytes are weight or multiplier for the sub-sample (MLT). Next 16 Bytes (3+3+10) comprise of NSS_SR, NSC_SR and MLT_SR pertaining to Subround wise multipliers. Last byte is for Newline character. (2) The Layout of data is given in the MS Excel-file lay68_sch100.xls. (3) For generating any estimate, one has to extract relevant portion of the data, and aggregate after applying the weights. (4) For all subround weights (or multipliers) are given at the end of each record from 133rd 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 field staff, Vol-I) subsample-wise weights (all subround multipliers) --------------------------------------------------- NSS = Bytes 127-129 (3 bytes) NSC = Bytes 130-132 (3 bytes) MLT = Bytes 133-142 (10 bytes, assumed two places of decimal) ----------------------------------------- All records of a household will have same weight figure. For subround wise weights (or multipliers) are given at the end of each record from 149th byte onwards. subsample-wise weights (subround multipliers) ----------------------------------------------- NSS_SR = Bytes 143-145 (3 bytes) NSC_SR = Bytes 146-148 (3 bytes) MLT_SR = Bytes 149-158 (10 bytes, assumed two places of decimal) ----------------------------------------- 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". (5) In the value fields (in Rs.) only the numeric figure is given in datafile. ---------------------------------------------------------------- Use of subsample-wise weights (all-subround multipliers) ---------------------------------------------------------------- For generating subsample-wise estimates based on data of all subrounds 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 final weight (or all-subround multipliers) as follows : final weight = MLT/100, if NSS=NSC = MLT/200 otherwise. ----------------------------------------------------------------------------- Use of subsample-wise weights (subround multipliers) ---------------------------------------------------------------- For generating subsample-wise estimates based on data of a particular subround, 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 subround multipliers) as follows : weight = MLT_SR/100, if NSS_SR=NSC_SR = MLT_SR/200 otherwise. ----------------------------------------------------------------------------- (6) 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) Segment Number = 32(1) Second Stage Stratum Number = 33(1) household Number = 34(2) Level Number = 36(2) Item Code = 38(5) ------------------------------------------------------------------------------- (7) List of Documents --------------------- General Information ----- README68_S100.txt Text Data Layout ----- lay68_sch100.xls Subsample-wise multiplier (all-subround) file layout for schedules 10 ----- multlay68_100.xls Subsample-wise multiplier (subround-wise) file layout for schedules 10 ----- multlay68_100sr.xls Blank schedule 0.0 ----- sch00-final_180411.doc Blank schedule 10 ----- Sch10_68th.doc Estimation procedure note and related tables for stratum composition for 68th round in the Common folder ----- EST68_final.doc State codes ----- State code.doc Ammendment to NIC 2008 ----- nic amendment_2008.pdf Please note that Blank schedules are in the folder 68v-2 within the Common folder.
