I imagine there could be a useful office in a city with ~20 people using it regularly and ~100 people interested enough in EA to come to some events, and I wouldn’t think of that city as an “EA hub”.
I also think eg. a London office has much more value than an eg. an Oxford or Cambridge office (although I understand all three to be hubs), even though Oxford and Cambridge have a higher EA-density.
