2. Things you need to know
What the data measures
The data measures the average custodial sentence length for offenders given an immediate custodial sentence by a court.
If an offender was sentenced for more than one offence, the data relates to the offence for which the offender was given the longest sentence.
Figures are based on the length of sentences given in court, not the length served by the offender.
The data includes:
- ‘indictable-only’ offences, such as murder or rape, which can only be heard in a Crown Court
- ‘triable either way’ offences, such as burglary or drugs offences, which can be heard in magistrates’ court or Crown Courts
Sentences are rounded to the nearest month.
Not included in the data
The data does not include:
- life sentences or other custodial sentences where there is no set end date (known as ‘indeterminate sentences’)
- ‘summary’ offences, such as motoring offences and minor criminal damage
The ethnic groups used in the data
The data uses the following ethnic groups based on the 2001 Census:
- Asian
- Black
- Mixed
- White
- Other (including Chinese)
Ethnicity wasn’t known for about 1 in 5 offenders. The data only includes offenders whose ethnicity was known.
