Some homicide trends from Scotland today.
A decade ago the city proper of Glasgow had a rate of around 5.7/100k making it the murder capital of Western Europe. It probably still is close to that title but with rates 60% down on 10 years ago.
With a population of 606,300 in the city proper, 14 homicides in 2015/16 (the year to March 31 2016) equates to a rate now of 2.31/100,000. If you take the whole of the Glasgow City Region which includes East Dunbartonshire, East Renfrewshire, Glasgow City, Inverclyde, North Lanarkshire, Renfrewshire, South Lanarkshire, and West Dunbartonshire you have a total of 29 homicides for a population of 1.8m, a rate of 1.61/100,000. Excluding the city proper the outer districts of the City region had 15 homicides in 2015/16 for 1.2m population, a rate of 1.25/100,000.
Those are all higher than the UK average but the city region as a whole is showing good progress. Most homicides are not gang/crime related but rather they are related to the city's historic culture of heavy drinking in working class areas with most homicides taking place within homes and committed by perpetrators who are acquaintances of the victims. Knives are the most common method and up to 70% of perpetrators were thought to be under the influence of alcohol. :|
Edinburgh has also seen some reductions though rates were never as high there, just 1 homicide in 2015/16 was a very good year, with a population of 495,000 in the city proper that is a rate of just 0.2/100,000 residents, down from over 2.0 in some years in the last decade.
