The county-by-county map above shows the percentages of residents who reported "Frequent Mental Distress" (FMD)--defined as 14 or more days of emotional discomfort, including "stress, depression and problems with emotion," during the previous month. Of note, Kentucky was the "saddest" state while Hawaii was the "gladdest".
And the map:
Strine, T. (2004). Risk behaviors and healthcare coverage among adults by frequent mental distress status, 2001 American Journal of Preventive Medicine, 26 (3), 213-216 DOI: 10.1016/j.amepre.2003.11.002
Looks like the bible belt reported the most FMD cases.
Interesting. The middle part of Arizona is redder than the rest. I wonder how much of that is Indian Reservations.
As a native to Arizona, I find the map immensely inaccurate. The reddened areas are of Yavapai, Gila, and Apache counties. Phoenix, our capital, is in Maricopa. Apache and Gila are far from well-populated, so I find it very unlikely they have more cases of FMD than Maricopa county. Yavapai county is possibly true due to all the suburbia that's grown up there, but it's still not likely to be worse than Maricopa. I'd expect Pinal county to the south of Gila to be high up there too, what with that including a large portion of the Phoenix Metropolitan area, along with a prison.
