More on Prevalence…
BPD is now recognized as a common disorder (it wasn’t in the early 1990s).

It is the most common of the personality disorders, with a prevalence rate of approximately 2–4% in the general population, accounting for 20% of people receiving inpatient mental health care and 15% of those receiving outpatient care

Grant et al, 2008, Friedel (accessed 2019):
“The results of a large, well-conducted study funded by the National Institute of Mental Health [Grant et al, 2008]* suggests that the lifetime prevalence rate of borderline disorder is about 6% of the general population, and appears to occur equally in men and women.”

*Prevalence of lifetime BPD was 5.9% (99% CI: 5.4–6.4)

Epidemiological evidence suggests that about 2% of the American adult population meets DSM criteria for borderline personality disorder (BPD; Swartz, Blazer, George, & Winfield, 1990). However, clinical experience suggests that BPD is often underdiagnosed in many treatment settings.
