Partly mapped: the map covers only part of the council, so no share is given. Other classes: the map records its own classes, so no share is given. Not applied: fewer than one address in ten here is on land whose planning scheme uses the overlay, too few to give a share; not a finding about the land. Each council page explains its figure.
