This zip file contains the Standard Area Measurements (SAM) for the health areas in England and Wales as at 1st April 2016 in CSV and XLSX format. This includes the Clinical Commissioning Groups (CCG), Local Health Boards (LHB), NHS Regions (Geography) (NHSRG), NHS Commissioning Regions (NHSCR), Public Health England Centres (PHEC) and Public Health England Regions (PHEREG). 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. (File size - 634 KB)Click the Download button to download the file
