Borderline Personality Disorder Statistics

GITNUXREPORT 2026

Borderline Personality Disorder Statistics

About 5.6% of U.S. adults meet criteria for borderline personality disorder at some point in their lifetime, and among those living with it, around 70% report at least one suicide attempt and roughly 75% self injure. The page also compares treatment evidence and health system impact, including why structured therapies like DBT can reduce self harm and why people with BPD may face far higher hospitalization and care costs than other psychiatric groups.

Nearly 6% of U.S. adults meet criteria for Borderline Personality Disorder at some point in their lifetime, yet the impact captured in studies goes far beyond diagnosis alone. Among people with BPD, about 70% report at least one suicide attempt and the risk of attempting suicide is estimated to be around 50 times higher than in the general population. Alongside that toll are patterns that often travel together such as PTSD, self harm, and heavy health care use, which is why the statistics can feel both stark and tightly connected.
