It would be almost impossible to determine how many serial killers the world has ever seen. Accurate records would only cover a couple hundred years. Before legalities and modern record keeping there would be little evidence on which to base the facts.
Estimates on more modern killers are frightening. At any given time, in America only, there may be 200 serial killers at work. It would probably be less in other countries(America seems to have more serial killing) but they will be there. In fact it is not uncommon for a killer to change countries. The chance of detection may be smaller if the killer keeps moving. There have been numerous instances where individuals come to America and begin killing or continue killing after having started elsewhere.

Although many killers have personality traits in common, there is not one single reason that people murder other people, and each situation is unique. Some murderers become serial murderers while others commit a single action.
