1. Main facts and figures

  • between 2010/11 and 2016/17, the rate of assaults per 100 young people in custody doubled for both White young people and for young people from all other ethnic groups combined
  • in 2016/17, there was an average of 18 assaults per month for every 100 young people in custody from the White ethnic group, and an average of 24 assaults per month for every 100 young people in custody from all other ethnic groups combined
  • in 2016/17, the rate of assaults by young people in custody from the Other ethnic group was about 1.3 times higher than that of White young people in custody
Things you need to know

Each young person carrying out an assault is counted, so a single incident can be counted multiple times. Individuals are often involved in more than 1 assault, so they can be included in the data more than once. This means that the rate per 100 young people in custody per month averaged across the year should be considered with some caution. The data does not show if an incident involved people from the same or different ethnic groups.

Estimates based on a larger number of prisoners are generally more reliable. Therefore, the smaller numbers of prisoners from ethnic minority backgrounds mean that estimates for these groups are less reliable than estimates for White people.

What the data measures

This data shows rates of assaults carried out by young people in custody by ethnicity. Each assault carried out 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.

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

The data includes young people held in:

  • young offenders’ institutions
  • secure children’s homes
  • secure training centres

The data is based on all assault incidents, but does not include information about staff or visitors who may have been victims, or be otherwise involved.

The data is taken from the Youth Justice Board for England and Wales (YJB) publication of Youth Justice annual statistics.

The ethnic categories used in this data

The number of young people carrying out assaults 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 (including White British and White ethnic minorities)
  • Other (all other ethnic minorities)

3. Methodology

The monthly population of the youth secure estate is based on the number of young people in custody at the beginning of the month, plus new admissions during the month. This is then averaged over the year and used to calculate the rate of assaults.

Figures do not include data where ethnicity is unknown.
