Korea ranks first in the world in per-capita spending on pornography, Newsweek magazine said Sunday.

As of 2006, each Korean spent an average of US$526.76 to watch porn, which was about 3.4 times more than Japanese people ($156.75) who came in second. Next were Finns ($114.70), Australians ($98.70), Brazilians ($53.17), Czechs ($44.94), Americans ($44.67), Taiwanese ($43.41), Brits ($31.84) and Canadians ($30.21), according to the magazine.

But it is unclear how credible the statistics are. Newsweek attributes them to a blog called "Ranking America" run by Mark Rice, the chair of American Studies at St. John Fisher College in Rochester, New York. They appeared on the blog in August of last year, and Ranking America says it got them in turn from a website called Top Ten Review, run by a software research and marketing firm.
