Population dives and climbs -- state of Michigan Census Dept. data (May 21, 2015)

from Michigan Live! online article:
Detroit, still the country's 18th largest city and easily the biggest in Michigan at 680,250 residents, continued to lose population in 2014, although at a slower rate than recent years.
Detroit shed an estimated 6,424 residents last year — about 1 percent of its population — and has lost an estimated 30,945 residents since 2010.
"We've seen Detroit losing population for a while now," said state Demographer Eric Guthrie. "Hopefully those populations losses are starting to be turn around. They're doing some things there."
Many of the state's biggest population gainers were townships — with Pittsfield in Washtenaw County and Meridian in Ingham County faring well in raw numbers — but Grand Rapids and Ann Arbor were notable exceptions to that trend.
Grand Rapids, Michigan's second-largest city, was the second biggest population gainer in 2014, adding an estimated 1,333 residents. It also ranks second in the state for total growth since 2010, adding an estimated 5,799 residents since that time.
