Notes
This the date at which a participant is first recorded (according to the record sources available to UK Biobank) at the location given in
Field 32223 and
Field 32224 (or the more precise, but highly restricted,
Field 32221 and
Field 32222).
Note that, when data is supplied to approved researchers, the array index of dates will not necessarily be in the same order as the dates themselves, since UK Biobank does not itself receive location data in chronological order.
This field supersedes Field 22700 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.
