know about Norway prison

That makes Norway's incarceration rate just 75 per 100,000 people, compared to 707 people for every 100,000 people in the US.

On top of that, when criminals in Norway leave prison, they stay out. It has one of the lowest recidivism rates in the world at 20%. The US has one of the highest: 76.6% of prisoners are re-arrested within five years.

Norway also has a relatively low level of crime compared to the US, according to the Bureau of Diplomatic Security. The majority of crimes reported to police there are theft-related incidents, and violent crime is mostly confined to areas with drug trafficking and gang problems.

Based on that information, it's safe to assume Norway's criminal justice system is doing something right. Few citizens there go to prison, and those who do usually go only once. So how does Norway accomplish this feat? The country relies on a concept called "restorative justice," which aims to repair the harm caused by crime rather than punish people. This system focuses on rehabilitating prisoners.

Take a look at Halden Prison, and you'll see what we mean. The 75-acre facility maintains as much "normalcy" as possible. That means no bars on the windows, kitchens fully equipped with sharp objects, and friendships between guards and inmates. For Norway, removing people's freedom is enough of a punishment.

Like many prisons, Halden seeks to prepare inmates for life on the outside with vocational programs: woodworking, assembly workshops.
