While the circumstances surrounding every suicide are different, the data presented throughout this section can be used as a guide to help identify and target programming towards the populations with the highest need for prevention of suicide and self-harm injury. Understanding how the different risk and protective factors interact, overlap, and impact different populations could help increase the effectiveness of suicide prevention efforts and warrants further investigation. For effective programming, prevention strategies should also address individual, relationship, and community levels of risk factors for greatest impact. In Part 3 of this report, specific strategies and recommendations for effective suicide prevention will be presented.
