America's Big Cities Get Smaller
Phoenix has overtaken Philadelphia as the nation's fifth largest city, underscoring decades of population losses in America's big industrial centers.
The nation's population has nearly doubled since 1950 -- adding about 150 million people. But of the 20 largest cities at mid-century, all but four have shrunk, some by a lot.
Detroit, Cleveland, Pittsburgh, St. Louis and Buffalo, N.Y., have all lost more than half their population in the past half-century.
