When you think about the happiest states in America, what do you imagine? Do you think of the care-free surfer bros of California? The always down to party citizens of New Jersey? Or what about the Mormons of Utah, who are always the nicest, happiest people you can imagine?

It's hard to believe the coldest state in America is also the happiest. This study must've been conducted during summer months. Also, I told you Mormons are happy people.

Some interesting notes in the study: Oregon has the highest share of adults with depression, while Hawaii has the least. However, Hawaii also has the worst adequate sleep rates in the country. The first three states with legalized recreational marijuana (Colorado, Oregon and Washington) are also the top three states in highest sports participation. Utah, Oregon and Rhode Island have the fewest work hours in the country, while Alaska, Wyoming and North Dakota have the most.
