Three colour mixing of 10,444 census wards on an equal land area map — software by author on an Archimedes computer.
Compare this map with the previous enumeration district cartogram (Plate LXVIII) to see how very different is the picture of the same statistics. Here we see great expanses of green where apparently both young and old reside together. It can also be seen that more older females inhabit what we know to be the more densely populated areas than males. The extremely low populations in Scotland produce spurious patterns in the mountains there. Areas of low population are given high prominence, while areas of high population are given low prominence.
