Three colour mixing of 129,211 census enumeration districts on an equal population cartogram — software by author on an Archimedes computer.
This shows a most interesting pattern. The three colours mix little in the picture, but appear in every region and city twisted around each other. The prosperous areas are coloured blue, the poor are coloured red. The middle of the country is dominated by skilled manual workers, a great many of whom were miners, still relatively well off in 1981. This picture shows the class distribution in Britain, and we can often see traces of it in the other images in this work. Look for the ring about the capital and the distinctive pattern at its centre. The shape of the West Midlands and the prosperous regions south of Manchester, across North Yorkshire and scattered about Scotland.
