This includes the Sub Integrated Care Board Locations (SICBL), Integrated Care Boards (ICB) and NHS regions (NHSER). 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).Click the Download button to download the files
