DETROIT, MI -- The city lost twice as many residents from July 2012 to July 2013 as it did the previous year, according to new population estimates from the U.S. Census Bureau.

The annual estimates indicate that after losing fewer than 5,000 residents and dipping below 700,000 in 2012, Detroit lost nearly 10,000 more the following year, bringing the latest number to 688,701.

Detroit remains the nation's 18th largest city, according to the Census Bureau.

Michigan gained over 13,000 residents from 2012 to 2013, according to the new figures, bringing its population to 9,895,622.

Warren and Sterling Heights, the third and fourth most populous Michigan cities -- behind only Detroit and Grand Rapids, both continued to gain residents last year.

Sterling Heights has been creeping up toward the third spot, reaching 131,224 in 2013, compared to Warren's 134,873, according to the new estimates.

Another Macomb County community, Macomb Township, is one of the fastest-growing places in Metro Detroit, gaining 5.1 percent when compared to the 2010 census, reaching 83,618 last year.

Detroit Mayor Mike Duggan said Thursday he expects to eventually reverse the Motor City's downward population trend.

"I am going to be judged on one thing," he told the Detroit News, "whether the administration can reverse that trend. We are totally focused on salvaging our housing stock and moving people back in the city."

Elsewhere in the state, Flint's population dropped below 100,000 for the first time since the 1920s, and Grand Rapids gained residents to reach 192,294 in 2013, according to the Census estimates.
