How many / which cities are included in the charts?
The cities are chosen according to their population. The pan-American and pan-European charts contain the 1000 largest cities within their respective areas. Where possible, all of the remaining charts contain all cities with a population above 1000. Some of the European nations have more than 1000 such cities – these are limited to only the 1000 most populous cities. The complete lists can be found via the US, Canadian, and European indexes.
