Please read this before proceeding To view this interactive map, most users will require a special piece of software, compatible with the emerging SVG graphic format. We recommend the free SVG Viewer by Adobe, available for Windows, Mac, and other operating systems. Users of Windows NT, 2000 or XP may require the assistance of their systems administrators to install Adobe SVG Viewer. Users of Microsoft Internet Explorer (IE) for the Mac will not be able to access this interactive map, due to issues with IE itself. SVG (Scalable Vector Graphic) is a relatively new data format, which combines the benefits of Flash with the flexibility of XML. SVG is recommended as a 'Web standard' by the World Wide Web Consortium. The Office for National Statistics is keen to receive feedback on this interactive map, and the use of the SVG format. If you have any comments, please email svg@ons.gov.uk I have SVG Viewer, take me to the map
