http://www.statistics.gov.uk/census2001/products_by_media_date.asp Look at the bottom under "Geography Products". The data we use at FillThatHole are: * Boundaries for all Output Areas in England and Wales in MID/MIF and Shapefile formats (DVD) * Output Area to higher areas & Postcode to Output Area lookup tables Mine arrived on DVDs in the post, free of charge. My point-to-authority search does: 1) Find the OAs whose bounding rectangles include the point. 2) If only one, then look up the authority. 3) If more than one, load the OA polygons and do point-in-polygon until one is found, then look up the authority. There are a few holes in the data, particularly where large rivers are, so I've tweaked the OA boundaries for a few of them as problems arise. Also the boundaries, being for people, run down the center of some roads. This isn't the same as highway authority boundaries, where a road is only maintained by one authority, the boundaries effectively running down the sides of roads rather than the middle.
