So sadly real answers are 22 SLC, 31 MDW, and most of the medium list!
And I would argue most of these airports are not hubs or even focus cities. Are they simply using hub as short hand for airport???
They're using "hub" in the US government sense. The US uses the "large hub", "medium hub", "small hub" monikers to classify airports. I don't know why the government uses that term instead of "airport" but Wikipedia is just copying that.
