United Kingdom prison population
The United Kingdom has three distinct legal systems with a separate prison system in each—one for both England and Wales, one for Scotland, and one for Northern Ireland. England and Wales has one of the highest rates of incarceration in Western Europe, with Scotland close behind: In 2006 an average of 148 people in every 100,000 were in prison, just ahead of Scotland with 139 per 100,000.
Using the figures below from 2009 and 2011, the UK prison population stands at around 97,000. As of October 4, 2011 the population of women in prison in the UK is 4,635.
A growing number of British prisoners have served in the armed forces. According to one recent study reported in the Guardian, there are now 8,500 former servicemen in prison, making up almost 10% of the prison population.
