What are the differences between the raw and derived databases and which should I use?
The raw databases contain the data as received from the survey questionnaires. The names of the raw databases begin with the prefix ‘raw’, for example, ‘rawhh’. The derived databases contain data that is adjusted in some way after it was received. These adjusted variables are clustered into datafiles with ‘DV’ in the name, for example, ‘DVHH’. For most users the derived data files are most relevant and user friendly, particularly as much of the data that is contained in the raw datasets is also represented in the derived datasets. If the raw data is used then great care should be exercised as the structure of these files is very complex (page 14 of the ESDS Introductory guide to the EFS provides more information).
