Percentages are about the same... Detroit maxed at 2 million, now they are at about 900,000.
Buffalo almost closed in on 600,000, now hovering at 270,000. Exact same percentage loss, or just right about at it... just a smaller scale.
If ol Hank Ford wasn't turned down by the Buffalo city fathers for his upstart little car company back in 1902ish... how different things may be.
