September is Suicide Awareness Month. It is a time to talk openly about suicide, recognize the factors that can increase risk and reiterate that support and connection matter.

For the autism community, this conversation is especially important. Research consistently shows that autistic people experience higher rates of suicidal thoughts, suicide attempts and suicide deaths than non-autistic people.

That does not mean that being autistic causes suicidal thoughts or behavior. 

Suicide is complex and influenced by many factors; but understanding the unique experiences that can contribute to suicide risk among autistic people can help families, friends, educators, healthcare providers, and communities recognize when someone may need support.

The numbers are concerning. 

Research demonstrates a significant disparity in suicide risk:

• A 2024 systematic review and meta-analysis involving approximately 10.4 million people found that autistic people had an estimated 2.85 times greater risk of death by suicide than non-autistic people. Researchers estimated approximately 13,400 excess suicide deaths among autistic people worldwide in 2021.
• A large meta-analysis found that approximately 37% of autistic people reported suicidal thoughts during their lifetime, while about 15% reported a suicide attempt.
• Autistic children and young people are affected as well. A systematic review and meta-analysis found that approximately 1 in 4 autistic young people reported suicidal ideation, while approximately 8% reported a suicide attempt.

These numbers are estimates, and researchers caution that studies vary in how autism and suicidality are measured. Nevertheless, the overall evidence is consistent: suicide is an important and urgent issue for the autism community.

Why might autistic people face greater risk?

There is no single explanation.

A growing body of research points to an interaction between mental health, social experiences, environmental factors and access to appropriate support.

Mental health matters, but it isn’t the whole story. Depression, anxiety and other co-occurring mental health conditions are associated with increased suicide risk among autistic people. That said, focusing exclusively on mental illness can miss important parts of the picture.

Research also identifies common autistic experiences experiences such as social isolation, bullying, harassment, adverse childhood experiences and difficulties accessing appropriate support as factors associated with suicide-related behavior.

This matters because many of these factors are not inherent to autism. They are experiences that communities can work to change.

Human beings need connection.

For autistic people, finding that connection can sometimes be difficult. Differences in communication, sensory experiences, social expectations and interests can create barriers to building relationships. Experiences of rejection, bullying, discrimination or repeatedly feeling misunderstood can compound those challenges.

A 2026 systematic review examining risk and protective factors for suicide in autistic people identified social isolation and social difficulties among important concerns. While research on protective factors remains limited, supportive social relationships emerged as a potentially protective factor.

That finding reinforces something we see every day in our communities:

Connection matters.

Having people who understand you, accept you, listen to you and make space for you to belong can make a meaningful difference.

Being understood can be part of prevention

Autistic people may communicate distress differently. A person experiencing significant emotional pain may not always describe it in the way a parent, teacher, friend or healthcare provider expects. This is one reason suicide prevention efforts need to be responsive to autistic people rather than assuming that a one-size-fits-all approach will work for everyone.

Recent research examining suicide-related care for autistic young people identified the importance of accounting for autism-related needs, engaging the autistic person in their care, involving families and caregivers appropriately and improving coordination and training across service systems. Researchers are also working to develop and evaluate suicide-risk assessment and safety-planning approaches specifically adapted for autistic people.

What can we do?

Suicide prevention is not only about what happens during a crisis. It is also about creating communities where people have opportunities to develop relationships, find belonging, access support and live meaningful lives.

We can:

• Create opportunities for genuine connection. Make room for friendships and relationships that don’t require autistic people to change who they are.
• Take changes in behavior seriously. Increased withdrawal, changes in communication, loss of interest in things someone usually enjoys or expressions of hopelessness can be reasons to check in.
• Ask directly when you’re concerned. Asking someone whether they are thinking about suicide does not “put the idea in their head.” A direct, compassionate question can open the door to an important conversation.
• Listen without judgment. You don’t have to immediately solve someone’s problems. Sometimes the most important thing you can do is listen and let someone know they don’t have to face a difficult moment alone.
• Make support accessible. Mental health and crisis services should account for communication preferences, sensory needs and other ways autistic people may experience and communicate distress.
• Build connection before a crisis happens. Peer support, social opportunities, community groups and trusted relationships can help reduce isolation and give people places where they feel known and valued.

Connection is part of the conversation

Suicide prevention can feel overwhelming. We cannot always know what another person is carrying, and we cannot single-handedly eliminate every risk factor; but we can create communities where people are less likely to feel alone.

We can notice one another.

We can listen.

We can make space for different ways of communicating.

We can create opportunities for friendship, belonging, and purpose.

And we can remind autistic people that they are valued members of their communities—not because of what they accomplish or how well they fit in, but simply because they are.

This Suicide Awareness Month, let’s continue building communities where autistic people can find support and meaningful opportunities for connection.

If you or someone you know is experiencing suicidal thoughts or is in crisis, call or text 988 to reach the Suicide & Crisis Lifeline. If there is immediate danger, call 911 or go to the nearest emergency department.

Autism Oklahoma programming–vocational, educational and social–is rooted in creating critical community connections and cultivating a sense of belonging. Our newest initiative, Peer Connector Education, trains adults who are impacted by autism (parents/caregivers, siblings, community leaders and autistic adults) to start and maintain support groups in their communities. Our first two trainings are taking place in Oklahoma City on September 21st and 22nd and in Tulsa on October 5th and 6th. Visit our events page to learn more and reserve your spot.
