Extraction of NSSO Data

-
The following post is basically designed for the understanding of extraction of NSSO Data.
It contains STATA codes for extraction of unit-level survey data from NSSO's 71st round on Health and Education consumption in the ASCII format given to users to .dta format of STATA.


About the NSSO data


The NSSO data is provided in ASCII format and is flat/line sequential, also called a fixed width file. The data is accompanied by an excel sheet with the details of the layout of the data. The entire dataset is provided in ten txt files covering eleven blocks of data.
To import any txt file into STATA, one has to first create a dictionary file (.dct) following the layout of the data, and then import it into STATA using the infix command through the dictionary file.


The STATA code for extraction:


infix dictionary
{

infix using "<insert file path to dictionary file>", using ("<insert file path name to .txt file>")

Weights of NSSO Data

-
Since the NSSO data are samples, the multipliers are used to generates survey weights so you can get population level estimates based on the sampled survey responses. 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. Apply final weight (or all-subround multipliers) as follows : final weight = MLT/100, if NSS=NSC = MLT/200 otherwise. Copy of readme file which is available with data with a note for the user 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 charac
