I lived in NYC for years. Definitely a high stress environment, but I can't say the people seemed less happy in general than folks elsewhere. Maybe less SAPPY. It maybe that they are happy but won't admit it.
I was never happy around tax time there. Federal, State,and City income taxes.
My home state of Florida was in the top five, lol. Hmm, is it the weather, or the philosophy of each place? Could it be Liberalism makes one miserable instead?
People in sunny, outdoorsy states ?Louisiana, Hawaii, Florida ? say they're the happiest Americans, and researchers think they know why. A new study comparing self-described pleasant feelings with objective measures of good living found these folks generally have reason to feel fine.
At the other end of the scale, last in happiness ? is New York state.
