2. Things you need to know
What the data measures
The data shows the number of assaults carried out by young people in custody, by ethnicity.
It also shows the average monthly assault rate for every 100 young people in custody.
'Young people’ are 10 to 17 years old. The data may also include some 18 year olds.
The data includes young people held in:
- young offenders’ institutions
- secure children’s homes and secure training centres (combined)
Numbers and rates are rounded to 1 decimal point, but were calculated using unrounded figures.
How assault rates are calculated
The assault rate is the average number of incidents for every 100 young people in custody each month, based on 12 months of data.
The ethnic groups used in the data
Data is shown for 2 ethnic groups:
- white ethnic groups, including white British and white ethnic minorities
- other – all other ethnic minorities
This is because the number of young people was too small to make reliable generalisations about specific ethnic groups.
Young people in custody report their own ethnicity, which staff then record.
Methodology
Read the detailed methodology document for the data on this page.
Some young people may be involved in more than one incident, in which case they will be included in the data more than once.
There are more white young people in custody compared with other ethnic groups. You can read more about how group size affects the reliability of data.
Data for young offenders’ institutions includes fights and assaults. Figures broken down by ethnicity are based on the number of assailants involved, not the number of incidents. A single incident may involve more than one assailant.
Data for secure children’s homes and secure training centres only includes assaults. It does not include fights. Incidents in which the assault victim fights back are counted as 2 assaults rather than one, as long as the victim was not acting in self defence.
Because of differences in collecting data on assaults, you should not compare assaults in young offender institutions with assaults in secure children’s homes and secure training centres.
