This product supplements the Output Area to higher areas lookup, and provides the best-fit of Output Areas to 2004 wards (that is, those wards which have underwent a boundary change through a Statutory Instrument made in 2003). It allows Census results such as Census Area Statistics for Output Areas to be aggregated to 2004 wards.

Additional files provide more accurate Output Area constitutions for a small number of unchanged 2003 wards in Milton Keynes, Pembrokeshire, Monmouthshire, Lancaster, North Norfolk and South Norfolk where the original constitutions were not based on the final correct ward boundaries.
