Comments
Calculating the predicted Ward and Registration zone populations involved
summing the predictions for all 1DM cells which lie in each Ward or Registration
zone polygon.
The error in Great Britain is greatly reduced using Ward level constraints.
(The same appears true for Italy and the synthetic registration constraints.)
Since the end of the projert the EU has enlarged.
