The different colours show the percentage of the box numbers recorded by Royal Mail in each Postal District that are present as a ref=* tags on an amenity=post_box node in OpenStreetMap. (Post boxes without a matching ref=* are not counted.) The underlying data is also shown in the table below. To view a more detailed map and data for a single district, click on the map above or use the links in the table below.
