Notes
This location information is based on the postcode for the address to which the participants invitation was sent. If the participant updated their home address during their assessment centre visit, then that postcode was used as the source instead.
The location co-ordinates use the Ordnance Survey (OSGB) reference. This East co-ordinate needs to be used in conjunction with the North co-ordinate in Field 20034.
These grid co-ordinates (to a 100m accuracy) will only be released following special approval. For most purposes, grid co-ordinates rounded to a 1Km distance will provide sufficient information on location of residence at assessment. These rounded values are found in Field 20074 and Field 20075.
