However, big population doesn't equal big teams. Otherwise we'd have Limerick and Galway in the premier without any trace of Bray, Finn Harps and Longford...
Look abroad as well: Leeds, Nottingham, Bristol, ... all big population centres, but their clubs are out of the big leagues since quite a while now (OK, they once have been in the premier division, but that's a different thing). More examples would include Venice, Napoli, Trieste, Izmir, Bursa, Archangelsk, Lvov, ...
whereas at the same time rather small places like Villarreal, Gueugnon, Guingamp, Wolfsburg, Chievo, ... have been surviving on top level and are quite stable.
