http://en.wikipedia.org/wiki/List_of...ers_by_countryI agree with you that the US list is extensive, but I don't think types of crime are specific to countries of origin. I think the list is more reflective of the sophistication of law enforcement in the countries rather than the existence of serial killers.
See for yourself and notice the U.S list is quite extensive.
Edit: Actually the list for U.K is pretty long.... wow! Originally Posted by Naomi4u

Just because we have the most listed doesn't mean other countries don't have a like percentage of serial killers.
Also, it depends on what you consider to be a serial killer. Is Hugo Chavez one? What about drug cartel bosses? Mexico has been rife with killings lately, yet lists only 5 persons on your list.
