Millions of sociopaths
Experts estimate 1% to 4% of people are psychopaths or have antisocial personality disorder
It’s impossible to know exactly how many people are psychopaths or have antisocial personality disorder. They are both men and women. They are found in all segments of society, all walks of life. What you really need to know is that there are millions of sociopaths, they can be anywhere, and watch out.
Dr. Robert Hare estimates that 1% of the population in North America are psychopaths, the term that he uses. The population of the United States is more than 305 million. That means, according to his standards, there are more than 3 million psychopaths in the country.
A related diagnosis is antisocial personality disorder (ASPD). This is the term used by the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders.
Mental health professionals generally estimate that 3% of men and 1% of women in the United States have antisocial personality disorder. That would be 4.5 million men and 1.5 million women, for a total of 6 million people. Psychiatrists generally refer to these people as sociopaths.
Dr. Hare believes antisocial personality disorder has a broader definition than psychopath. In other words, he says all psychopaths have antisocial personality disorder, but not everyone diagnosed with antisocial personality disorder is a psychopath.
In The Sociopath Next Door, Dr. Martha Stout says 4% of the population are sociopaths. That would add up to 12 million of them in the United States.
As you can see, estimates are all over the place. The Lovefraud Risk Calculator projects the number of sociopaths in a community. The calculation assumes that between 1% and 4% of the U.S. population are psychopaths or sociopaths.
