2011 boundaries

The digital vector boundaries for 2011 output areas, super output areas (LSOA and MSOA), workplace zones and Census merged wards for England and Wales are available for download in three formats from the ONS Open Geography Portal.

Boundaries for most geographies are created at full, extent and generalised (to 20 metres), clipped formats. Further information on the these formats can be found in the downloadable file available on the Open Geography portal. Output areas, lower layer and middle layer super output areas are also supplied in the 'full, clipped' format on the Open Geography portal.

The boundary types produced are designed to be used in different contexts (such as analysis or visualisation).

Built-up areas and built-up area sub-divisions, are only available in one format - generalised, grid.

These boundaries are for use in geographical information systems to carry out spatial analysis or visualisation.

It is important that users understand which boundary type they require prior to download by reading the boundary guidance document contained in the Downloads section.

All these products are supplied under the Open Government Licence and Ordnance Survey Open Data terms and conditions.
