Prison population: Social Indicators page.Jump to full report >>
Between 1900 and 2017, the average prison population has increased five times. In September 2017 the prison population of England and Wales stood at 85,348, similar to annual monthly average in recent years.
As at December 2016, the most frequent length of sentence being served was a determinate sentence over 4 years. Around 43% of prisoners were serving this type of sentence. About a quarter were serving determinate sentences between 1-4 years.
The latest Ministry of Justice projections suggest that prison population will remain stable to June 2019, but then increase by 1,600 places above the current level to 88,000 in March 2022.
England and Wales had 156 prisoners per 100,000 population as at September 2017. This was an increase compared to 146 in 2014, but similar to 153 in 2011.
