Howe exactly is it "much lower" though? How should we quantify it? They are all in the low single digits. Is it really meaningfull to use language like "it is twich as high" or "three times higher" when the absolute difference is only in the range of 2-3? When you get into small numbers, saying something is twice or three times larger tends to make things sound larger than they truly are. For example, say country A has a homicide rate of 0.5, and country B has one of 1.8. This means country B has a rate 3.6 times higher than A. Does B have a problem?
Whether it's a large number or a small number depends entirely on the arbitrary choice of what units you choose to use.
I know some posters here have compared Canada's rate to the US as an example that the US has a problem. Yet Canada has a murder rate that is over two and a half times larger than Austria, and over five times higher than Iceland. Does that mean Canada has a problem?
Sure... any murder is a problem. The question is how significant it is relative to other problems.
Going by
these stats, if the US managed to reduce its homicide rate by 50%, it would mean that an additional 2.35 people per 100,000 per year would not be murdered. OTOH, if Canada reduced its homicide rate by 50%, we'd only save an additional 0.8 people per 100,000 per year.
And I might be going out on a limb here, but it seems to me that the lower the homicide rate, the more difficult it would be to lower it. With a high rate, the "quick win" measures are often apparent. When the rate is lower, it's the more difficult or less obvious steps that remain to be done.
... which, again, doesn't mean that murder isn't a problem in Canada, just that the priority should be proportional to the magnitude of the problem.
