Breakdowns

What this measures

The mean sentence length, in months, of prisoners released from a determinate sentence in England and Wales in the calendar year, all ethnicities.

What this doesn’t measure

Sentences passed in the year, time actually served (published in the same table), or indeterminate and life sentences.

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.
