Starting a multiyear (usually spanning several IRL years) save in England Tier 10. I've understood there is a small link between supporters/attendance and a city's population. Bought the in-game editor and it seems all clubs in Tier 10 had the same max attendance. However, there is also population size taken into account, which I'm understanding has an influence for how fast max attendance can grow following a club's growing reputation. Simply said, that would mean that a club in London would grow faster in attendance than a club in the middle of nowhere.
However, I can't find in the in-game editor what a club's accompanying population size is. This is technically something that can be done manually, but its eg pretty up for debate what the interpretation is of eg clubs located in London suburbs. In addition, I would expect this to be data somewhere available in the database. Is this something I simply can not find in the in-game editor, and is there a way to otherwise find this information somewhere in FM's files?
