Self-harm by young people in custody
1. Main facts and figures
- in 2017/18, the rate of self-harm by White young people in custody was just over 5 times that of young people from all other ethnic groups combined

- there were 3.4 incidents of self-harm per 100 young people from all other ethnic groups combined
The ethnic categories used in this data
The number of young people in custody involved in incidents of self-harm was too small to draw any firm conclusions based on specific ethnic categories. Therefore, the data is broken down into the following 2 broad categories:
- White – White ethnic groups (including White British and White ethnic minorities)
- Other – all other ethnic minorities

Self-harm is measured as the rate per 100 prisoners. The figures are taken from prison population monthly snapshots at the start of each month and averaged across a 12-month period.
The data is checked, but as with all large administrative surveys errors and omissions can occur.
Percentages have been rounded to 1 decimal point. Due to this, some figures may not add up to 100.
Counts have been rounded to the nearest whole number. All calculations have been made using unrounded figures.
See the Youth justice annual statistics for unrounded figures and the percentages calculated from them.
