Donald Trump has been taken to task for claiming, in his speech announcing the United States would exit from the Paris climate “treaty,” that “I was elected to represent the citizens of Pittsburgh, not Paris.” Numerous people have pointed out that Trump did not carry the city of Pittsburgh; it voted for Hillary Clinton by a margin of 75 to 21 percent. They might have added that surrounding Allegheny County, taken as a whole, voted 56 to 39 percent for Clinton over Trump.

But it’s also true that Trump did carry the Pittsburgh metropolitan area, which by government definition includes Allegheny, Armstrong, Beaver, Butler, Washington and Westmoreland Counties. After all, when people mention a city’s name, they are often referring not just to the area within the municipal limits of the central city, but to the larger metropolitan area.
