The New Hampshire Occupational Health Surveillance Program recently completed an analysis of New Hampshire suicide death cases from 2018 to 2022 by demographics and employment (industry and occupation).
Suicide, defined as death caused by self-directed injurious behavior, is ranked the 12th leading cause of death overall in the U.S, claiming the lives of over 45,000 people in 2020. The suicide rate in the U.S. increased 35% from 10.4 per 100,000 population in 2000 to 14.2 in 2018 (National Institute of Mental Health, NIH, 2023).
In New Hampshire, in 2017, suicide was the 8th leading cause of death (with a suicide rate of 19.0 per 100,000 population) -- higher than the national average (New Hampshire Division of Public Health Services & Injury Prevention Center at the Children’s Hospital at Dartmouth- Hitchcock, 2018).
Suicides from 2018-2022
- There were 1,165 suicides in New Hampshire from 2018 to 2022, accounting for 1.8% of all deaths occurred in the five years, with both the number and percentage decreasing over the five-year period (See Table 1)
