The distribution of graduates in Britain, 1981 (Colour).

Three colour mixing of 129,211 census enumeration districts on an equal population cartogram software by author on an Archimedes computer.

Almost half the country is white as no graduates live in the ten percent of households sampled from those districts. What is left is subdivided by the activity and sex of the graduate, in what is really a two colour mix. There is little pattern to be seen, except perhaps more graduates working around London and more working age female graduates not working in the Scottish highlands (this category was chosen as it was the only one which could be compared with a cell in the 1971 census tables).
