Dementia Wandering & Safety: What the US and Australian Data Actually Show

How common is wandering in dementia?

Wandering is one of the most-cited safety concerns in dementia caregiving. In the United States, the Alzheimer's Association estimates that 6 in 10 (60%) people living with dementia will wander at least once, and many do so repeatedly — this is the primary, most-cited figure on wandering prevalence, though it comes from a caregiving advocacy organisation rather than a government population survey.

Dementia Australia offers similar guidance for Australia, estimating that around 60% of people with dementia will wander on at least one occasion, describing it as a potentially life-threatening behaviour. This Australian figure is a useful, directionally-consistent data point, but it comes from an advocacy organisation, not a government or peer-reviewed source, and has not yet been corroborated by Tier-1 (government) data — so it should be read as supporting context for the US figure above, not as an independently confirmed rate.

What happens when a person with dementia goes missing

Wandering becomes a public safety event when a person with dementia goes missing and a search is required. The most detailed picture of what these episodes actually look like in Australia comes from a peer-reviewed study in the Australasian Journal on Ageing, which analysed 130 dementia-related missing-person cases reported in the Australian media between 2011 and 2015 (average age 75), published in 2018.

The study found that 62% of people went missing on foot, and 66% were last seen at home — meaning the search most often begins from a familiar, everyday location rather than an unfamiliar one. Of the people who were found, 60% were found well, 20% were found injured, and 20% were found deceased. These outcomes are drawn from cases serious enough to be reported in the media, so they should not be read as the outcome for every wandering incident — most wandering does not escalate into a media-reported missing-person search — but they show clearly what is at stake once an episode does become one.

Dementia prevalence in Australia: the government numbers

Government data give the clearest picture of how many people in Australia live with dementia today, and how that number is expected to change. The Australian Institute of Health and Welfare (AIHW) estimates that 425,000 Australians were living with dementia in 2024 — approximately 266,000 women and 159,000 men — equivalent to 16 people per 1,000 in the population.

Dementia prevalence rises sharply with age. AIHW data show a rate of 84 people per 1,000 among those aged 65 and over, climbing to 292 people per 1,000 among those aged 85 and over. AIHW also projects the number of Australians living with dementia to more than double, from just under 425,000 in 2024 to nearly 1.1 million by 2065, as the population ages.

Most people with dementia are not in residential aged care. AIHW figures (2022) show about 2 in 3 (66%) people with dementia live in the community rather than in residential aged care, while 54% of permanent residential aged care residents have dementia. Community living is the norm for most people with dementia — which is exactly the setting in which a wandering incident is most likely to first be noticed, or missed, by family rather than paid staff.

Why this matters for people living alone or aging in place

The government and academic data above point to the same underlying picture: most people with dementia live in the community, not in a residential facility, and the risk of a serious wandering episode is real enough that researchers have specifically studied its outcomes. For an individual managing early-stage dementia while living independently, or a family supporting a parent or partner who does, the practical safety question is rarely about the pendant-and-button model built for a fall. It is about noticing, quickly, when something has changed in someone's daily pattern — including the day a person leaves home and does not return when expected.

None of the figures above measure how often a missed daily check-in specifically predicts a wandering event; the Australasian Journal on Ageing study describes outcomes of confirmed missing-person cases, not a check-in-based prevention method, and none of these statistics should be read as evidence that any app prevents or detects wandering. What the data collectively support is a narrower, honest point: dementia is common, mostly managed in the community rather than in aged care, wandering is a widely-cited and common behaviour at some point in dementia, and when an episode does escalate to a search, the outcome is genuinely uncertain. That combination is exactly why any low-friction layer of daily awareness is worth having for someone living independently with a cognitive health concern in the household.

Where I'm Alive's free daily check-in fits

I'm Alive does not detect wandering, track location, or replace supervision for someone in a later stage of dementia — nothing in the data above suggests a daily check-in app changes those risks, and we make no such claim. What it offers is a simple, free daily safety net: the person checks in once a day, and if they do not check in by their own chosen time, their chosen contact is alerted that something may be wrong.

For someone in an earlier stage of dementia who is still living independently, or for a family member keeping an eye on a parent who lives alone, that one daily signal is a low-friction way to know the day started normally — and a missed check-in is a prompt to call or visit sooner, rather than discovering a problem hours or days later.

The core daily check-in is free, forever. A one-time $4.99 Lifetime upgrade adds an optional daily 'all good' note to one chosen contact. For those who want a dedicated layer of emergency-contact alerting and escalation built on top of the daily check-in, Protect Me is $29.99 per year, and Protect Me On The Move is $39.99 per year. None of these plans are a dementia-specific or wandering-specific safety device — they are a general daily check-in system that anyone living independently, including someone managing early-stage dementia or a family member concerned about one, can set up in minutes.
