I came across the above map on Wikipedia showing the incarceration rate (number of prisoners per 100,000 people) for each country. Greenland caught my eye since its rate is much higher than Denmark, which it’s part of. It turns out that incarceration in Greenland is quite interesting:
The Greenlandic prison system runs with a uniquely open model. Prisoners must report to prison between 9:30pm and 6:30am each day, but may go to work, visit relatives and complete errands while in the community. They also may hunt with firearms if they are escorted by a prison guard. Prisoners have keys to their own cells, as this is regarded as a form of privacy. A failure to attend prison will result in 7 days in solitary confinement once the escapee returns. […] There are presently 160 places in the Greenlandic prison system.
