When you read up on U.S. political basics, you can’t help but come across the detail that many of the people in cities in the U.S. seem to lean left, yet what isn’t as clear is why and what influences their concentration in cities/urban areas.
Cities don’t exactly appear to be affordable, and left-leaning folks in the U.S. don’t seem to necessarily be much wealthier than right-leaning folks, so what’s contributed to this situation?
So if we set aside those that simply lived there already & so that affected their leaning, then the other part may be the employment opportunities?
Which then may shift the question to matters concerning the employers’ location decisions, so that’s another route to research, I suppose.
Employers go where they can find a well-educated workforce that will sustain them. And round and round we go.
Economic location geography is a lot more complicated than that (not every business is labour-intensive, cluster economics, IO logistics et cetera). Political geography of population also isn’t equal or similar to economical geography, given that social factors like class or race and discourses around sometimes heavily distort those maps we imagine.
