Every dot is a planning site that a community contested. There is no basemap: the shape of England is the sites themselves.

What we measured

We harvested 852 campaign sites from the Community Planning Alliance’s national campaign map. After the audit in the next entry, 652 remain. Each one was cross-referenced against live open-government spatial layers from 33 APIs held by 8 government bodies, then coloured by deprivation band using the English Indices of Deprivation 2025: 87 sites in deciles 1–3, 321 in deciles 4–7, 242 in deciles 8–10, and 2 with no decile.

What it shows

Where campaigns exist, not where planning conflict is. This map is the sampling frame for every entry that follows.

What it doesn’t show

A convenience sample, not a population. Putting a campaign on a national map takes digital literacy and organising capacity, so the least resourced communities are the least likely to appear. We do not know which way the bias runs. Each dot is also plotted at the postcode centroid given on the campaign’s form (“please use a nearby postcode if you do not know it”), not at the site itself, so every distance in this series carries a position error that we have not yet measured.

Corrected again 12 November 2026 after a check of the data pipeline: sites are plotted at postcode centroids, and the claim that the sampling bias is conservative is removed.
