1. Main facts and figures

  • in 2016/17, the rate of self-harm by White young people in custody was just under 3 times that of young people from all other ethnic groups combined
  • there were 12.8 incidents of self-harm per 100 White young people in custody per month, compared with 4.4 incidents of self-harm per 100 young people in custody from all other ethnic groups combined
Things you need to know

The data records the number of occasions on which an act of self-harm was reported, not the number of individuals that self-harmed, nor how often individual young people harmed themselves.

Estimates based on a larger number of people are generally more reliable. The larger number of young people in custody from the White ethnic group means that estimates for this group is more reliable than estimates for all other ethnic groups.

What the data measures

This data measures rates of self-harm by young people in custody, broken down by ethnicity. Each incident of self-harm by a young person in custody is counted and their ethnicity recorded. Rates are expressed per 100 young people in custody per month (on average across the financial year) from 2010/11 to 2016/17.

Self-harm in this data is defined as any act where a young person deliberately harms themselves, regardless of how they do so, what their intent is, or how badly they injure themselves.

'Young people’ are aged between 10 and 17 years. The data may also include some 18 year olds.

The data includes young people held in:

  • young offender institutions
  • secure children’s homes
  • secure training centres
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 (taken from prison population monthly snapshots at the beginning of each month, including new admissions, averaged across a 12-month period).

The data is reviewed, but as with all large administrative surveys errors and omissions can occur.

Rounding

Rates per 100 young people in custody are rounded to 1 decimal place.
