In 2016, Scotland already had one of the lower homicide rates in Europe but by 2018, it had fallen even further to become one of the lowest and is below that for England & Wales. I can’t find 2018 figures for all of those above but, assuming no major changes downward, Scotland now has a level only bettered by Norway, Iceland and Ireland.
The homicide rate for Scotland in 2018 was 0.91 per 100 000 putting it lower than globally low-crime Sweden, Denmark and Finland. Even in 2016, the rate for England & Wales was higher at 1.22 per 100 000 but this seems likely rise again for 2018 with a massive 14% rise being reported in the media. The 2018 rate for Sweden, also, seems likely to have risen dramatically in the wake of frequent fatal attacks between organised criminals from different minority groups.
