Record length is 308.

# : 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 143 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). Last byte is for Newline character.
     
(2)  The Layout of data is given in the MS Excel-file lay68_sch010_typ1.xls.
   
(3)  For generating any estimate, one has to extract relevant portion
     of the data, and aggregate after applying the weights.
     
(4)  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, 
     NSS 68th Round, Manual for field staff, Vol-I)

     
     NSS,NSC and 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 an 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. 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 (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.
    
-----------------------------------------------------------------------------

(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)
