Borderline Personality Disorder - Key Statistics and Prevalence


Borderline personality disorder (BPD) is characterized by pervasive instability in moods, interpersonal relationships, self-image, and behavior. While a person with depression or bipolar disorder typically endures the same mood for weeks, a person with BPD may experience intense bouts of anger, depression, and anxiety that may last for only a few hours to a day.

  1. In the United States, recent research has shown that 1.6% of the population has BPD.
  2. That number may seem small, but when you consider just how large the United States is, you may realize that 1.6% represents quite a large number of people. That percentage means that over four million people have BPD in America alone.
  3. In a recent study, over 40% of people with BPD had been previously misdiagnosed with other disorders like bipolar disorder or major depressive disorder.
