Notes
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 coordinates use the Ordnance Survey (OSGB) reference. This north coordinate needs to be used in conjunction with the east coordinate in Field 32221 and the date in Field 32220.
Access to these grid coordinates (to a 100m accuracy) will only be granted in exceptional circumstances where they are deemed essential for a particular research question. For most purposes, grid coordinates rounded to a 1km distance will provide sufficient information on location of residence at assessment. These rounded values are found in Field 32223 and Field 32224.
This field supersedes Field 22703 as part of an update to home location history data to correct some problems with the original dataset. Please see the description on Category 150 for more information.
Coding 2535 defines 3 special values:
- -999 represents "Grid co-ordinates could not be assigned to address"
- -998 represents "Participant's address flagged as invalid"
- -997 represents "Grid co-ordinates redacted"
