File Types and Names

Distribution Files

Survey datasets are distributed as compressed .ZIP files. A distribution .ZIP file contains multiple working files which generally include a data file, various data definition files, and other documentation. This page includes instructions on how to work with distribution .ZIP files. The video below provides a quick introduction to DHS datasets.

Working Files

The types of "working files" that are contained in each distributed .ZIP file include a data file, various data definitions, and other documentation. The exact type of files that are included will vary depending on the associated data type and file format.

Working files must be extracted from the distributed .ZIP file.  The files can be extracted using PKUNZIP, Winzip, or other data compression software. You can download the Winzip Evaluation Version for free.

Distribution File Naming Convention

An individual .ZIP file is distributed for each dataset type (e.g. household, women, men, children, couples, etc.) and file format (e.g. hierarchical, flat, SPSS, SAS, Stata.) Each .ZIP distribution file is uniquely named with a standard naming convention. The video below provides guidance to new users understanding the standard naming conventions used in our downloadable datasets. 

Dataset files are named according to the following convention: [CC][DD][VV][FF][DS].ZIP

Code Description:
[CC] Country Code
[DD] Dataset Type (e.g. HR-Household, PR-Household Member, IR-Women, MR-Men, BR-Births, KR-Children under 5, and CR-couples)
[VV] Dataset Version (First Character - DHS Phase) (Second Character - Release version)
[FF] File Format (eg. FL-Flat, SV-SPSS, DT-Stata, SD-SAS)
[DS] Data Structure for SPA (SR: SPA Recode | SP: SPA Raw)

To give an example of how distribution files for a survey are organized, the following table shows the available files, along with the names that they are given for the Kenya 2003 DHS survey.
