In the book “Triumph of the City,” by Edward Glaeser, he states that ” Detroit’s decline is extreme, but it’s hardly unique. Eight of the ten largest U.S. cities in 1950 have lost at least a sixth of their poplulation since then. Six of the sixteen of the largest cities in 1950 – Buffalo, Cleveland, Detroit, New Orleans, Pittsburgh, and St. Louis – have lost more than half their population since that year. In Europe, cities like Liverpool, Glasgow, Rotterdam, Bremen, and Vilnius are all much smaller than they once were. The age of the industrial city is over, at least in the West, and it will never return. Some erstwhile manufacturing towns have manages to evolve from making goods to making ideas, but most continue their slow, inexorable declines.
