Here's the full chart.
The bottom of the (state) barrel is unchanged from 2012 with West Virginia (50th), Kentucky (49th) and Mississippi (48th) bringing up the rear. The top of the chart has a new number one with North Dakota -- and its booming oil economy -- jumping all the way from 19th in 2012 to first in 2013. South Dakota moves from 12th to second happiest in 2013. Of the top ten happiest states, only one -- Washington -- is located on either of the nation's two coasts. (The middle of the U.S. may be flyover country but people who live there seem to love it.)
Here's the well-being index in map form. Green states are the 10 most happy followed by blue, yellow, orange and red.
When it comes to specific categories on which single states repeatedly excel, the reports says:
"Colorado, for example, is always at or near the best in the nation for the lowest obesity rate. Utah has the fewest smokers. Massachusetts has boasted the highest level of residents with health insurance all six years [of the index]. New Jersey has the lowest levels of depression. And Vermont rules America every year in produce consumption."
Putting on my political hat (yes, I have one and, no, I never really take it off), some of the early voting states in the presidential process are among the happiest too. (Politics makes people happy!) Iowa is the 9th happiest followed closely by New Hampshire at 10th. South Carolina, on the other hand, isn't all that happy (38th) and Nevada is in the middle of the pack (26th).
