Best and worst

Ten at each end, from the public data behind StreetOwl. Every table says what it ranks — councils, NHS trusts, forecourts, 1 km squares, towns — because most of these figures are not published for single postcodes, and a table that pretended otherwise would be guessing.

Rankings are ours; every figure is the publisher's, named under each table. Tables are rebuilt each morning from the newest data StreetOwl holds. Where a table could not be rebuilt it shows the last one that could, marked as such. Nothing here is a verdict on a place — a bill, a wait or a reading, with its date. About StreetOwl.
