Not only has Detroit been ranked as America's most stressed city, but it can also stake its claim as being the unhappiest.

A new statistical ranking of cities lists Detroit as the nation's unhappiest.

So, according to WalletHub, Detroit is now the country's most stressed, unhealthiest and unhappiest city.

For the study, WalletHub considered 150 U.S. cities for the rankings, which Detroit ranked at No. 150 for.

Michigan, in general, hasn't fared well in WalletHub's in-depth reports, as Detroit was named the aforementioned America's most stressed and unhealthiest city, while Ann Arbor and the Motor City were recognized as two of the country's rudest.

Grand Rapids slotted in as the No. 56 happiest place to live as Michigan's only other representative on the list. Grand Rapids did rank as having the fifth-highest volunteer rate in the country, according to the study.

The study on happiness in cities focuses on several specific measurable, there is a particular focus on depression rate, income growth and personal time spent each day. WalletHub reports it looked at 30 different measurables in its report.

Detroit scored extremely low on adequate sleep rate, obesity rate, sports participation, income growth, and separation and divorce rate.

"Location indeed plays a hand in our pursuit of such an elusive condition. For years, researchers have studied the science of happiness and found that its key ingredients include a positive mental state, healthy physique, strong social connections, job satisfaction and financial well-being," the report reads. "However, there's a caveat on that last one:

"Wealth follows happiness -- but only up to an income level of $75,000 a year. Any higher, and money ceases to influence a person's contentment with life."

The rankings were decided using a 100-point scale by breaking it down into three wide-ranging categories; emotional and physical well-being, income and employment, and community and environment. The topics were broken down into 30 different metrics.

Detroit scored a 27.78 and last-place finish in emotional and physical well-being, and income and employment. To put the painful ranking in comparison, Cleveland, the second unhappiest U.S. city, scored a 36.80.

That 9-point difference between No. 149 and 150 represents the same difference in score between No. 149 and Np. 130.

Grand Rapids scored a 56.9 with a middle of the pack emotional and physical well-being, with two top 40 rankings in income and employment, and community and environment.
