How Many People Are Exposed to Suicide? Not Six

TLDR

The claim that six people are left behind after each suicide has been widely cited for over three decades despite lacking empirical support. The study aims to calculate a more accurate number of people exposed to each suicide using data from a random‑digit dial survey. The authors surveyed 1,736 adults, of whom 812 had lifetime suicide exposure and reported age and number of exposures. Each suicide exposed an average of 135 people, indicating a large circle of individuals who may need clinical services or support.

Abstract

It has long been stated that six people are left behind following every suicide. Despite a lack of empirical evidence, this has been extensively cited for over 30 years. Using data from a random‐digit dial survey, a more accurate number of people exposed to each suicide is calculated. A sample of 1,736 adults included 812 lifetime suicide‐exposed respondents who reported age and number of exposures. Each suicide resulted in 135 people exposed (knew the person). Each suicide affects a large circle of people, who may be in need of clinician services or support following exposure.
