The Region of the Americas is the only region that has recorded a sustained increase in suicide mortality over the past two decades. Suicide disproportionately affects younger people: 58% of deaths occur before the age of 50 and it is the third leading cause of death among adolescents aged 15–19 years. Rates are highest among older adults, particularly men aged 80 years and older. Indigenous Peoples and rural populations experience disproportionately high suicide mortality in several countries. 

According to the most recent Global Health Estimates, the age-standardized suicide mortality rate increased from 7.8 per 100 000 population in 2000 to 9.2 in 2021, corresponding to more than 100 000 deaths in 2021. Between the 2014 baseline of 8.6 and 2021, the most recent year for which data are available, the average annual percentage change was an increase of 0.9%, whereas achieving the regional target would have required an annual reduction of approximately 1.0%. 

This trajectory stands in sharp contrast to the PAHO Strategic Plan 2020–2025 target, which anticipated a reduction to 7.0 per 100 000 population by 2025, while the projected rate for 2025 is 9.5. At the country level, there are signs of both progress and regression: between 2010 and 2021, 12 countries recorded statistically significant declines, 12 remained stable, and 8 recorded significant increases. Therefore, this indicator is on the wrong track. 

Among 33 countries surveyed, 15 (45%) have standalone national suicide prevention strategies, while 18 countries have integrated suicide prevention within broader mental health policies. Most strategies were published in 2021 or later, substantially limiting the observable population-level impact within the 2010–2021 analysis window, given the documented lag of several years before measurable effects are seen. 

The regional suicide mortality rate among men (14.7 per 100 000) is 3.7 times higher than that among females (4.0). Despite this, the evidence points to a paradox, with higher rates of attempted suicide among women but greater lethality among men, largely driven by differences in methods used and help-seeking behaviors. Interrupted time-series analyses across the Region show that the adoption of a suicide prevention strategy is significantly associated with sustained reductions in mortality. Following implementation, suicide rates declined annually by 3.0% annually among males and 2.55% among females. Limited implementation of interventions to restrict access to means of suicide remains a critical gap, despite robust evidence of their effectiveness. 

These findings provide valuable evidence that can be used to strengthen suicide prevention in the Region of the Americas, particularly as this indicator continues to be a regional priority under the PAHO Strategic Plan 2026–2031.
