The unemployment rate in the U.S. city of Detroit dropped to 8.4 percent in April this year, the lowest since 2001, showed preliminary figures released by the U.S. Bureau of Labor Statistics on Thursday.

Although the 8.4-percent jobless rate is still higher than the statewide rate of 4.7 percent in Michigan and the national average of 4.4 percent, it has after all plummeted from a high of 27 percent in January 2010. It is definitely a good news for the city after it went bankrupt in 2013.

The city added 964 jobs in April and roughly 1,500 in March, and is expecting to employ additional 40,000 local residents in the next five years, according to Jeff Donofrio, director of the Workforce Development Agency of Michigan.

"There's no doubt that jobs are moving back into the city," the Detroit News quoted Mayor of Detroit Duggan as saying. "We created a climate where everybody feels welcome in Detroit, and there's a level of investment that you haven't seen in probably 50 years."

With over 18 billion U.S. dollars in long-term debt, the city of Detroit filed for bankruptcy in July 2013, making it the largest city in U.S. history ever to do so. A federal judge ruled that Detroit was eligible for bankruptcy protection in December in the same year.

Detroit is a "Motor City," with Ford, General Motors and former Chrysler and now Fiat Chrysler Automobiles NV having their headquarters there.
