Product notes
The boundaries were initially released in Summer 2003. Whilst the boundaries remain unchanged, they were re-issued in January 2004 to correct some errors in the postcode to Output Area lookup table, and to remove some technical problems with boundary intersections experienced by users of the MID/MIF format files.
