Sources & methodology
Every value comes from one of the open datasets below and is computed the same way for every town. Each section names how precise its values are: town-level, modelled or regional. Distances are straight lines from the town centre, and amenities are counted within 1.2 km of it. Read the full methodology.
"Who Riachos suits" lines come from fixed rules applied to every town in the same way. A rule only uses values that are modelled or better, and each line shows the numbers that triggered it. How the rules work.
