All flows are drawn between the 17 level II European regions on an equal population cartogram, which took place between 1975 and 1976. The sizes of the circles at the origins and destinations are in proportion to the in and out flows, while the widths of the arrows also show flows in both directions — software by author on an Archimedes computer.
The picture shows that the highest migration flows were between metropolitan counties and their surrounding regions. Some large flows from and to the South East region can be made out. The flows are sorted so that arrows between places which are neighbours appear uppermost in the network of lines. This is a particularly useful technique allowing movements between more places to be seen. Already, with just seventeen places, too confusing a picture is presented by drawing all the streams.
