Key statistics and figures

  • Someone is reported missing every 90 seconds in the UK  
  • Almost 170,000 people are reported missing every year  
  • There are over 320,000 reported missing incidents every year  

How many people go missing each year?  

  • Missing people: of the 170,000 people reported missing nearly 97,000 are adults and nearly  70,000 are children
  • Missing incidents: of the 320,000 reported incidents, more than 130,000 incidents are adults and almost 190,000 incidents are children
  • Looked after children are at high risk of being reported missing. 1 in 10 looked after children are reported missing compared to 1 in 200 children. Looked after children who are reported missing will be reported on average 6 times  

Most of the people who are reported missing may be experiencing some kind of vulnerability or risk. This can be exacerbated by being missing, particularly where someone goes missing more than once.  

How did we come up with these figures? The statistics were developed by Missing People using statistics in the National Crime Agency report 2021-22. The figures used are the number of incidents (I.e. the total number of reports of someone going missing, including missing incidents) and the number of individuals (I.e. number of individual adults and children reported missing, which does not reflect repeat missing).


Research shows that police data is likely to be a significant underestimate. There are limitations to the NCA data, including differing recording practices and incomplete data, and some people will not be reported missing to the police at all. Research suggests that as many as 7 in 10 children are not reported to the police when they go missing. Little is known about adults who are not reported missing.  

What is ‘missing’? 

There is not one multi-agency definition of missing, however for definition for police is “anyone whose whereabouts cannot be established will be considered as missing until located, and their well-being or otherwise confirmed.”

Why do children and young people go missing?

There are a wide range of reasons why adults and children go missing, and often there is more than one cause. Some of the most common reasons for children to be missing are:

Relationship breakdown

  • 3 in 10 missing adults  


4 in every 10 people with dementia will go missing at some point, often unintentionally  

Financial problems

Escaping violence

  • 1 in 50 missing adults

The most common issues raised in conversations with adults contacting our helpline are:

  • Homelessness
  • Mental health

  • Problems at home
  • Risk of suicide
