The map

Black crosses are ACC churches. Shaded circles are growth corridors — suburbs where the bigger the circle the more people are arriving, and the darker it is the higher the planting priority. A green ring marks a volume growth corridor: fast growth AND a large number of people, the best places to plant. Amber diamonds are permitted homes — counties with 2,000+ homes permitted in 2023–25, the neighborhoods that are about to exist. Switch the layer to ask a different question of the same suburbs — who lives there, what they earn, what they studied, what they speak at home. Pick a SA4 region to break the picture down.
