Residences

To understand how many people are affected by a boundary change, we counted the number of residences in areas falling outside of current boundaries or into new boundaries. For this, we used Ordnance Survey residential address data. The number of residences is not the same as the number of voters. But since there is no detailed electorate data, it serves as a proxy.
