The ONS have also produced a tool to ‘Build a custom profile’ visualisation. This allows you to search for a specific borough or ward by typing it into the ‘Find an area or postcode’ box and then allows you to build a profile based on your selected area. There are 34 different indicators that can be included in the report and although England is used as the default comparison option this can be changed for a more local comparison.
