About UK Standard Area Measurements (SAM)
The 2011 SAM provide a definitive list of measurements for administrative areas in the UK.
The land measurement figures provided are defined by topographic boundaries (coastline and inland water), where available.
Measurements are reviewed annually and include information up to the end of December.
The measurements have been produced in conjunction with the following UK government statistical organisations and independent mapping agencies: National Records of Scotland; Northern Ireland Statistics and Research Agency; Office for National Statistics; Ordnance Survey®; Land & Property Services and Ordnance Survey of Northern Ireland®.
The SAM User Guide explains differences in methodology and base mapping between these agencies.
SAM is provided in a MS Excel spreadsheet. The User Guide, contained within the product, provides further details.
