This location information is based on the postcode for an address at which the participant is believed to have been resident, derived from a number of sources.
The location co-ordinates use the Ordnance Survey (OSGB) reference, rounded to the nearest Kilometre. This North co-ordinate needs to be used in conjunction with the East co-ordinate in Field 22702.
For most purposes, grid co-ordinates rounded to a 1Km distance will provide sufficient information on location of residence at assessment. Research proposals that require location details to a finer level of granularity (i.e. 100m) should request Field 22701 and Field 22703, however special approval will be required to release the more detailed information.
In some cases participants will appear to be at the same location at consecutive times. This occurs because there is a difference of under 1Km in the distance between two consecutive locations according to the more granular data.
There are no tabulations involving field 22704.
