This page includes choropleth maps of the English counties, detailing the geographical distribution of Robin Hood-related place-names and localities from three different perspectives. The dataset on which they are based is set out in a table below.
The choropleth maps
A choropleth is "a thematic map in which areas are shaded or patterned in proportion to the measurement of the statistical variable being displayed on the map".[1] It thus resembles a heat map, but unlike a heat map in which variation is in principle continuous, it displays data averaged over discrete geographical regions, in this case the English historic counties. On all three maps, a bi-polar colour progression is used, counties with values above the mean – set to index 100 – being coloured a progressively darker green, while those below are coloured a progressively darker red. Ideally colour gradation should appear linear, but since there are a few outliers in the data this would lead to either the colour steps not being clearly distinguishable or loss of resolution among values closer to the mean. Intervals are therefore broader for areas well above mean value. A brief description of each map follows.
