Migration Flows between Family Practitioner Areas
on a Population Cartogram
in 1976
Flows involving more than
one in two thousand of the areas'
population shown.
63% of all flows shown.
Figure 6.17 Flows between 1975 and 1976 drawn between these 97 areas on
an equal population cartogram. At this level almost two-thirds of migrants are
represented and Scotland is included, linked most to London (more so than to its
neighbours). A division can now be seen running across the country, separating
the high propensity to migrate within the South from the much more insular North.
