The 2025 Annual Report to the Community presents the most recent data available for suicide deaths (2024, unless otherwise noted), emergency department encounters for suicide attempt/intentional self-harm and suicidal ideation (2023), and local survey data for additional measures of suicidal ideation (2023–2025). The report uses data on suicide ideation from the California Health Interview Survey Data (CHIS) by age, sex, gender, sexuality, race, and immigration status.

Findings:

• In 2024, San Diego County had 377 suicide deaths (rate: 11.4 deaths per 100,000 people). This was a 4% decrease in rate compared to 5 years prior in 2020, though a 3% increase in rate from the previous year of 2023. 
• Suicide death rates were highest among residents who were male, ages 70-79, non-Hispanic (NH) white, or living in East Region. 
• In 2023, emergency department (ED) encounter rates for nonfatal suicide attempt/intentional self-harm were highest among residents who were female, ages 10-17, NH Black, or living in Central Region. ED encounter rates for nonfatal suicidal ideation were also highest among residents who were female, ages 10- 17, NH Black, or living in Central Region. Firearms continue to be the leading method of suicide. 
• Suicide deaths by firearm were more common among residents who were male, ages 45+, NH American Indian/Alaska Native, NH Black, or NH white, and for those living in all HHSA regions except for Central Region, where asphyxia was most common. Asphyxia was the second leading method of suicide overall. 
• Suicide affects everyone, though some demographic groups are disproportionately impacted. The Suicide Prevention Council has identified 12 priority populations for suicide prevention efforts. These include residents who are Asian American or Pacific Islander, Black or African American, Latinx, LGBTQIA+, Middle Eastern or South Asian, military or veterans, Native American or American Indian, re-entry or justice-involved, seniors or older adults, suicide attempt survivors or those with lived experience, survivors of suicide loss, and transitional age youth (16-25 years).
