Mental disorders and civilization go together, I reckon. And economic development is a good if rough and ready proxy for civilization. Thus I searched the World Wide Web for the epidemiology of mental disorders, but I came across some useful information about the epidemiology of depression only. Compiled by the World Health Organization, it was based on data from 2004, which covered one-hundred and ninety-two countries. America was foremost in the ranking, and so I felt comfortable with my initial hypothesis. I started by checking the ranking of the countries that used to be part of former Yugoslavia, most of which I know reasonably well. As it turned out, Slovenia was thirteenth, Croatia twenty-fourth, Bosnia and Herzegovina sixty-second, Serbia and Montenegro sixty-seventh, and Macedonia sixty-eighth. By the way, Kosovo was nowhere in the table. Even though I was surprised by the high places of both Slovenia and Croatia, the ranking fit my expectations very well. Economic development and depression matched each other quite markedly, indeed. Only then I noticed that Japan was hindmost in the ranking. Also, India and Pakistan were fifth and sixth. But I was most surprised by Portugal and Greece, which were ranked one-hundred and eighty-eighth and one-hundred and ninetieth, pretty close to Japan. Mental disorders and civilization may well go together, but I need more information about the match. Important though it is, depression is only one among many mental disorders. The lists I found on the World Wide Web go into hundreds of them. I have my work cut out for me.
