Imagine for a moment that every single person living in the city of San Jose, Calif., plus an additional 150,000 or so, just up and left. Vanished. Poof. Gone. Leaving their homes, business buildings and factories behind.
That is, in effect, what has happened to the city of Detroit, according to 2010 U.S. Census data. The city that boasted 1.8 million residents in 1950, and was the nation’s economic engine for most of the 20th century, now is home to 714,000 people, a population loss of 1.1 million — with a 25 percent drop in the last decade alone.
