Standard Area Measurements for Electoral Areas (December 2018) in the UK

This zip file contains the Standard Area Measurements (SAM) for the electoral areas in the United Kingdom as at 31 December 2018. This includes the Westminster Parliamentary Constituencies and European Electoral Regions. All measurements provided are ‘flat’ as they do not take into account variations in relief e.g. mountains and valleys. Measurements are given in hectares (10,000 square metres) to 2 decimal places. Four types of measurements are included: total extent (AREAEHECT), area to mean high water (coastline) (AREACHECT), area of inland water (AREAIHECT) and area to mean high water excluding area of inland water (land area) (AREALHECT). The Eurostat-recommended approach is to use the ‘land area’ measurement to compile population density figures.
