BPD is estimated to affect 2-3% of the general population, but affects 11% of patients seen in outpatient clinics, and as many as 20% of hospitalized psychiatric patients.
About 8-10% of people with this disorder die by suicide.
It is believed that BPD may be the result of a combination of factors, including a biologic or genetic vulnerability that interacts with stressful events in the early family environment.
