In 2025, the risk of self-harm and suicide is still being shaped online, even as platforms remove enormous volumes of harmful content. YouTube alone reported removing 8.4 million videos in Q2 2023 for violating self-harm policies, yet studies and meta-analyses keep finding links between exposure, cyberbullying, and higher rates of suicidal thoughts, attempts, and depressive symptoms. This post brings those pieces together, from U.S. and global suicide baselines to the mechanisms that may turn online harms into real-world outcomes.
Key Takeaways
- 2,628 deaths were registered in the United States in 2021 with an underlying cause of death coded as “intentional self-harm by other and unspecified means,” and social/relational factors are discussed in CDC suicide prevention materials that connect online harms to suicide risk
- 47,000 people died by suicide in the United States in 2019 (CDC), illustrating the scale of baseline suicide mortality that online harms can exacerbate
- 703,000 people worldwide died from suicide in 2019 (WHO), providing global context for how online harms can influence self-harm outcomes
- Google reported removing 8.4 million videos in Q2 2023 for violating policies on self-harm (YouTube transparency; quarterly enforcement), quantifying continuing moderation
- Reddit’s transparency reporting states it removed 99% of content for certain categories before users were able to report it (reported in enforcement methodology), indicating proactive moderation capacity
- YouTube’s transparency report shows that in 2023, an increasing share of policy removals were initiated by systems rather than user reports (reported in policy removals methodology tables)
- In a systematic review, 3.4% of adolescents reported recent suicide attempts and exposure to self-harm content was associated with increased risk of suicidal ideation/behavior (meta-analytic evidence; study reports pooled effect sizes for exposure)
- A meta-analysis found that social media use was associated with a 13% increase in depressive symptoms (standardized mean differences pooled across studies), relevant because depression is a risk factor for suicide
- A meta-analysis reported that cyberbullying is associated with higher odds of suicidal ideation and suicide attempts among youth (pooled odds ratios reported in the study), linking online harassment to self-harm outcomes
- A JAMA Pediatrics study found that online bullying victimization was common, and associations with suicidal ideation were reported with adjusted odds ratios for bullied youth
- In a U.S. study, students who reported cyberbullying were more likely to report suicide attempts (study reports prevalence and adjusted effect sizes)
- A 2020 report found that 31% of adolescents reported seeing content that could encourage self-harm on social platforms (platform exposure prevalence reported), which can influence suicidal behavior
- In 2024, YouTube had 2.5B logged-in monthly active users (industry metrics summarized by DataReportal), relevant to suicide/self-harm content exposure risk
Millions of youths face online self harm content and cyberbullying, and evidence links it to depression, ideation, and suicide attempts.

Interpretation
Public Health Burden Interpretation
With 47,000 suicides in the United States in 2019 and 703,000 worldwide, the public health burden linked to social media is especially concerning because in one U.S. student sample 18.8% seriously considered suicide in the past year and CDC materials explicitly connect online harms to suicide risk.

Platform Safety Systems Interpretation
Across platform safety systems, moderation appears to be getting more automated and proactive, with Google removing 8.4 million self-harm videos in Q2 2023, Reddit reporting it removed 99% of certain category content before users could report it, and YouTube showing that in 2023 a growing share of policy removals were triggered by systems rather than user reports.
