By studying the two maps it is fairly
straightforward to see where change has occurred,
although the process can be time consuming and doesn't
give any idea as to how the change translates into
gains and losses to the business.
The best way to understand this financially,
is by using a heat map as shown below.

The heat map compares, by Postcode sector, the value
of all customer types in terms of spend between
the two time periods. The darker the shade of red
the greater the financial lose for the Postcode
sector. The darker the shade of green indicates
the growth areas. From this map and further
geographical and statistical analysis, reasons for
change can be determined and corrective marketing
strategies put in place.
