It looks like there are a few things the top states have in common and which distinguish themselves from the bottom. Top states either:
- Have few or no extremely large metropolitan areas. LA, Chicago, and NYC are all in bottom 5 states.
- Have sunny weather. Note that the high ranking cold states are relatively sunny in the winter; Montana, Wyoming, etc. and don't have the miserable months of gray that states around Lake Erie and Lake Michigan do.
- Have reasonably stable, non-industrial economies. Some aren't necessarily prosperous, but they're not economically unstable, either
- Are states with few transplants, and tend to be places where family is likely to live nearby. Notice that states you'd expect to do well (Nevada, Texas, Colorado) are often places that people also complain about "so damned many Californians moving in". Californians can make anyplace into hell. :tongue2:
Bottom states are almost all:
- Industrial, or formerly industrial.
- Have large, densely populated aging cities.
- In the winter gray belt, where you have don't a beautiful clear winter with mountains and skiing, just a salty, gray, miserably slushy mess.
- Have experienced a lot of economic upheaval, both good and bad; Michigan unemployment, California boom-and-bust prosperity.
- Have a lot of transplant population.
Interestingly enough, there is some correlation with the red state, blue state thing, but only because red state, blue state correlates with the presence of large metro areas, as BKB pointed out. The larger the percentage of small town and rural voters there are in a state, the more likely it is to be "red" or Republican. Some major exceptions to red vs blue on that list are:
Hawaii. Very blue, yet #2 overall.
Indiana. Very red, yet near the bottom.
As far as ignorance being bliss, most of the bottom states also contain the leading colleges and universities in the US, and the leading states contain the fewest. We've been talking in the B10 thread about the AAU -- if you look at where AAU schools are located and where states place on the happiness list, you're going to find a HUGE number of them in the very bottom states. Oddly enough, that might be the highest correlating single factor.
Does knowledge make you miserable? Moving to philosophy in 5...4...3... :-D
