1981 Equal Population
Grid Squares on
an Equal Area Map
Each square contains
30,000 people
Figure 3.21 This map was created using enumeration district populations. The
darker lines encompass areas of three million people and 100 smaller 'squares'.
If you did want to map population grid squares on a normal map, perhaps this lat-
tice would be most appropriate. London, as expected, contains the mostly densely
packed single large population square. That square is home to three million
people.
