Guernsey and Alderney · 2002–2022 · Counts only
In twenty years the whole 10–19 age group holds fewer than ten suicides.
Suicides are typically expressed as "# per 100,000 per year," but we can not do that for this jurisdiction.
This chart groups age "10-19" suicides, but it's important to note that 10-19 is really not what we are looking at. Suicides under 10 are extremely rare, and suicide rates increase with age all the way to age 19. So the "pool" of 10-19 is describing 19 year old suicides more than it's describing 10 year old suicides, by a large margin. It is best to think of the "10-19" number as including young children but mostly being older adolescents.
Be cautious comparing jurisdictions like states or countries; there are huge differences in culture, methods available, ethnicity, poverty, and other variables. It's even been shown that religious coroners are less likely to adjudicate findings of suicide than non-religious coroners!
The Bailiwick’s own mortality table counts deaths by suicide or injury of undetermined intent, by age and sex, across the twenty years 2002 to 2021. In the 10–19 age group it records five male deaths and fewer than five female (the table suppresses any cell below five, so the true figure for girls is somewhere between one and four), and the whole age group holds between six and nine deaths in twenty years.
At all ages, 104 over the same twenty-year period, 77 male and 27 female, which the table itself averages as four men and one woman a year.
A freedom of information response from the States of Guernsey in May 2023 covers the six years 2017 to 2022 and answers the question about children in a single sentence: there were no deaths due to suicide or injury of undetermined intent in those aged under 18 registered in Guernsey and Alderney over that period.
Between six and nine deaths in twenty years, in an age group of a few thousand children, cannot establish a rate easily. I'm glad we have data from G&A, but it is not comparable data (i will only publish rates if there are at least 15 suicides in total accumulated over time).
The definition of suicide in these counts include "injury of undetermined intent" alongside intentional self-harm.
The defensible sentence is a count and a period: fewer than ten young people aged 10 to 19 died by suicide or undetermined injury in Guernsey and Alderney in the twenty years to 2021, and none under 18 in the six years to 2022.
Every figure on this page is a count, printed as its source printed it. Nothing here is a rate, so nothing here is pooled, fitted or compared, and the page computes nothing at all. Expand for the full citation.

Every page on this site was looked at by me, one at a time, before it was published. This is exactly what that involved, and what it did not.
What I checked
What I did not
Automated checks ran over every page and I read their output. A language model was used on some pages to suggest things worth a second look; nothing it produced is published, and nothing it said stands as a finding on its own.
A review is a point in time. If the data behind a page changes afterwards, the page does not ship again until it has been looked at again — that rule is enforced when the site is deployed, not left to memory.
