True, but there are no Scottish or Northern Irish teams on there in spite of the UK in the title. Livingston, Bonnyrigg, Methil and Elgin (among others) have league football teams and populations of under 100000.
The description explicitly states that the quiz is about PL/EFL clubs. It's not easy to come up with a title that satisfies all the nitpickers. Feel free to suggest a better title if you have one.
