What this measures
The mean sentence length, in months, of prisoners released from a determinate sentence in England and Wales in the calendar year, by the ethnicity recorded on entry to prison, with "Not stated/ Unrecorded" as its own category.
What this doesn’t measure
The offence mix, previous convictions or pleas behind the sentences, sentences passed in the year, or time served.
Important caveat
The average sentence length is the mean determinate sentence, in months, of prisoners released from a determinate sentence in the calendar year, by the ethnicity they gave on entry to prison (Prison-NOMIS). It describes the sentences of people leaving prison that year, not the sentences passed that year, and excludes indeterminate and life sentences. Differences between groups reflect the mix of offences, previous convictions and pleas as well as any difference in sentencing, none of which this table separates. "Not stated/ Unrecorded" is a published row.
