• About half of autistic children try to wander or bolt at least once after age 4, according to a parent survey covering 1,218 autistic children. In that survey, 26% went missing long enough to cause concern.¹
• Drowning caused 91% of US wandering deaths in autism in 2024.² If someone goes missing, call 911 at once and search nearby water first.
• Families combine several protections: an emergency plan, door and window alarms and locks, ID, swimming lessons, a tracker, and behavioral support. As of October 18, 2026, National Autism Resources’ door and window alarm 5-pack costs $79.99.

Wandering, also called elopement, is when someone leaves a safe area or the adult responsible for them.³ In autism, it can start in the toddler years and carry on into the teens, or come back later. Most deaths after wandering are drownings. Nearly half of the deaths with a recorded search time came after a search of an hour or less.⁴ National Autism Resources is a Missouri store that sells autism tools to families and schools, and it carries two alarms designed for wandering. Safety groups advise combining several protections, such as home security, close supervision, swimming lessons, and tracking technology.²

Why autistic children wander

Parents in a 2012 Pediatrics survey run by the Interactive Autism Network could pick more than one reason their child left.¹ Their most common answers:

• The child enjoys running or exploring: 53%
• The child is heading to a place they like: 36%
• The child is escaping an anxious situation: 34%
• The child is escaping uncomfortable sensory input: 30%
• The child is pursuing a special interest: 30%

The National Autism Association (NAA) says wandering can be a way for children to communicate, either by moving toward something they like or away from things like noise, crowds, fears, or demands. Anxiety and stress can increase the chances of wandering. The NAA lists high-risk times such as changes in routine, travel, holidays, crowded events, unfamiliar places, moving to a new home, and overnight hours. Most children wander from their own or another home (74%), followed by stores (40%) and classrooms or schools (29%).¹

Wandering rates by age

A CDC study of 4- and 5-year-olds found that 60.4% of children with autism wandered, compared with 12.4% of children in the general population.⁵

For many children, wandering stops after early childhood. CDC researchers followed 258 autistic children into their teen years. Of these, 45% had never wandered, 41% only wandered in early childhood, and 14% wandered at least once as adolescents.⁶Adults wander too, though research on them is limited. Most cases in NAA’s review involved people 19 or younger. The share of cases ending in death increased again for adults aged 25 to 29.⁴

In the 2012 survey, half of the parents whose children wandered had received no advice on handling it, and 62% said it kept the family from activities outside the home.¹

Drowning and other dangers

Drowning is the leading cause of death when a child with autism wanders off. In the 2012 survey, 24% of children who went missing were in danger of drowning and 65% in danger of traffic injury.¹

In NAA’s review of 808 cases from 2011 to 2016, drowning caused 71% of deaths and traffic 18%.⁴ NAA says drowning caused 91% of US wandering deaths in 2024. On average, NAA says, seven children with autism die each month after wandering.² The National Center for Missing & Exploited Children (NCMEC) reports that at least 98 children and young adults with autism were found dead in 2025. Of those, 88% had drowned, and 90% of those who drowned were 10 or younger.⁷

In 2017, Columbia University researchers looked at US death records. They found that suffocation, asphyxiation, and drowning made up 79.4% of injury deaths in autistic children.⁸ Children with autism are often said to be 160 times more likely to die from drowning than other children. The senior author, Guohua Li, gave that figure in the university’s press release.⁹ However, it is not in the published paper.

NAA’s drowning-risk scale puts missing children with autism aged 10 or under at the highest level. Children who don’t speak or speak unreliably are at that level too.² NAA also lists heat stroke, hypothermia, falls, and hot cars as dangers.

How to prevent wandering

CDC groups its prevention tips under plan, prevent, and teach.³

A written emergency plan

Write down what everyone does if your child goes missing, and keep a current photo and description ready for police. NAA’s free Be REDy booklets include a Family Wandering Emergency Plan. Learn your child’s warning signs, such as looking toward the door, and use Google Maps to find the nearest water source.

Door and window alarms, locks and fences

The CDC recommends fences and door locks, and NAA also suggests simple door and window alarms. An alarm warns you when a door opens. A lock or fence makes it harder to get out. NAA’s review describes an 8-year-old who stacked beanbag chairs to reach a lock and let himself out.⁴ Caregivers of the teens in CDC’s study most often responded to wandering with home locks or alarms (30.6%).⁶

National Autism Resources sells two products for this, as of October 18, 2026:

• Door/Window Alarm 5-pack, $79.99. Five adhesive alarms, $16 each, that sound when a door, window, or cabinet opens, with chime and buzz settings. Each resets when the door closes and takes three AG-13 batteries.
• Stop Strip Alarm System, $95.99. A yellow strip with a stop sign that attaches across a door frame with Velcro, as a visual cue. An alarm sounds if someone walks past it, and it includes a 9-volt battery.

Neither product page from National Autism Resources shows customer ratings yet. Shipping is free for orders over $89, so the 5-pack by itself does not qualify. Laminated Stop cue cards are available for $2.99 to mark doors that are off-limits.

ID on your child

CDC advises keeping ID on your child, such as a bracelet or an information card. The American Academy of Pediatrics (AAP) also recommends medical alert tags and a name on clothing. National Autism Resources doesn’t sell ID products.

Swimming lessons

In the Columbia press release, Li said swimming classes should be a top priority. The AAP says swim lessons designed for autistic children can lower the risk of drowning, but no lesson can make a child completely safe from drowning. Ask your local pool or YMCA about lessons for children with developmental disabilities, including practice swimming in clothes and shoes.

GPS and radio-frequency trackers

A tracker can help you find a child who has already wandered. NCMEC says it is just one tool, since technology can fail or be removed. In the CDC’s study of teens, only 8.3% of caregivers used a tracking device.⁶ National Autism Resources does not sell trackers. Our comparison of GPS watches for kids with autism and our AngelSense review look at different trackers, including those that attach to clothing, and their monthly plan prices.

Behavioral support and school plans

Function-based treatment starts by figuring out what the child gets from wandering, like getting something they want or avoiding a demand. In a 2025 trial with 76 autistic children aged 4 to 12, a 12-session caregiver coaching program based on this approach improved elopement severity more than general parent education. However, it did not do better on the main measure of the trial, which was a hyperactivity score. A blinded evaluator found that 31.6% of children improved, compared to 2.6%.¹⁰ Ask your child’s doctor about a board certified behavior analyst (BCBA) or psychologist who treats elopement.

At school, NCMEC recommends having a written plan for what staff should do if your child leaves the classroom. You can also include wandering in your child’s Individualized Education Program (IEP). At home, NAA suggests creating a quiet retreat, like a tent. National Autism Resources sells a Sensory Tent for $149.99.

Telling neighbors, school staff, and first responders

Tell neighbors, relatives, and teachers about your child and the places they head for, such as water or roads. NCMEC suggests introducing your child to local police. Some 911 centers use Smart911, a free profile. When you call from a registered phone, it shows your child’s photo and needs to the call taker.

If your autistic child goes missing

Act right away. NCMEC says most drownings happen within a few minutes, a few hundred feet to half a mile from where the child was last seen.⁷

1. Call 911 immediately. Say your child has autism and may not answer to their name.
2. Search water first. Check pools, ponds, creeks, and ditches nearest the last known location.²
3. Call NCMEC at 1-800-THE-LOST (1-800-843-5678) once 911 has been called.
4. Hand over your plan, with the current photo and the places your child is drawn to.

Children may hide from searchers and might run again after being found, so NCMEC recommends keeping the child in sight from a safe distance.⁷ Most wandering cases do not qualify for an AMBER Alert, which covers abductions.⁴

Paying for alarms, trackers and safety programs

Free programs cover some of the cost, and Medicaid waivers cover trackers in some states. Status as of October 18, 2026:

NAA hasn’t posted a restock date for the box, which is limited to one per family. National Autism Resources accepts school purchase orders and scholarship accounts.

Each state sets waiver coverage. North Dakota’s autism waiver began covering a tracking device for children prone to wandering in February 2024.¹¹ Some private insurers have reimbursed a tracker, case by case. The CDC says doctors should document wandering with diagnosis code Z91.83, so ask for it on your child’s record.³ Our guide to getting AngelSense for free covers waivers and grants step by step.

Kevin and Avonte’s Law, signed in 2018, funds grants to police, other public agencies, and nonprofits for tracking technology and wandering-prevention programs. Families don’t apply, and the FY2026 round closed in October 2026.¹²Your police department can tell you whether it gives out devices.
