%0 Report %A Marcotte, Dave E. %T The 988 Suicide and Crisis Lifeline and Suicide %D 2026 %8 2026 Oct %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 19038 %U https://www.iza.org/publications/dp19038 %X In July 2022 the ten-digit National Suicide Prevention Lifeline was replaced with a dedicated three-digit number, 988. This followed a precipitous rise in the suicide rate, especially among youth. Suicide is now the second leading cause of death among Americans aged 15 to 24. In this paper, I estimate the effect of 988 on youth and overall suicide rates. I show that the rollout of 988 increased the number of calls to suicide hotlines and the share of calls that were answered. Nonetheless, I find no evidence that 988 reduced suicide mortality. Using multiple identification strategies, I find no reduction following the national rollout in July 2022, nor do I find evidence that state-level improvements in call answer rates reduced suicide. These findings do not imply that 988 has been ineffective: the rollout clearly improved hotline access and response rates. However, I find no evidence that it reduced emergency-department visits for injuries caused by self-harm. %K evaluation %K prevention %K suicide
