You are quite right in young people going abroad to study and never coming back. There are about 20.000 either full or half Faroese people living in Denmark right now. It gets even worse because older people tend to move back home, which means. Use of free schooling here, then making zero money here to pay taxes, and in the end move back a few years before their pension to houses they have inherited from family. We don't have pr0perty tax here.

There is at the moment a 2000 female deficit to make the population 50/50.

The crime rate is pretty low yes. Last murder was many years ago, not counting two or three accidental shootings (at least deemed accidental) and car or machinery deadly accidents, some with alcohol involved. I don't remember any riot ever. A r@pe or really serious fighting once in a while. Some domestic violence. In my lifetime (32 years) I remember one bankrobbery at night and two armed robberies (stores). A single suicide every 3-5 years. Break ins and other theft and unfortunately some vandalism happen far to often though.
