An entry, European Prison Populations, informs us that "... According the Council Of Europe's Annual Penal Statistics issued in September 2013, Russia has the highest ratio of prisoners in its population, with 475 out of every 100,000 inhabitants serving time in jail. This is effectively ten times the rate of incarceration in Iceland, which has 47.2 prisoners for every 100,000 inhabitants..." with an accompanying graphic.
This is the sum total of the 'article', so one wonders what the message is intended to be. Just a simple factoid, or is this supposed to be more meaningful? One wonders...
Considering that this is from Radio Free Europe/Radio Liberty, it's not much of a stretch to believe that this factoid was put out there to make an unflattering comparison between Russia and Europe, and to illustrate a negative point about Russia.
Unfortunately, if one conflates a high prison population per 100,000 with a negative view of the country in question then what are we to take from the following (source)?
