Data rooms

One room per flagship dataset: what it is for, every field, how much it covers, and what you may reuse.

What a room holds

Each room states the date of its data, read from the data itself, a dictionary of every field its pages show, coverage counted from the data, a short method that links the full one, its sources, and what may be reused. Lists compiled by others, such as published team valuations, are shown as pages and never offered as files. The full method for the metro scores is on Methodology.
