The Motor City was home to 1.9 million people in 1950, at the time
nearly identical in size to Los Angeles. Today, 700,000 inhabit Detroit,
or less than a fifth the size of L.A. That works out to 2.2 people
leaving Detroit every hour, 24 hours a day, for the last 63 years. If
the number of people who left Detroit in the last 60 years formed their
own city, it would be the nation's ninth largest, ahead of Dallas, Texas.

2.2 people leaving Detroit every hour,

Hmmm, wonder what % of that is leaving in a box because of drive-bys.

Again, just curious.
