So exactly what do you mean by tiny?

If Norway had the same homicide rate as the whole of the US in 2019 (as it doesn't seem they've release the 2020 ones yet), according to the FBI[1] the homicide rate in the US was 5.0 murders per 100,000 people. Norway has a population of 5.4 million.

So for Norway, that would have been 270.

Does that seem like a fluctuation?

You're severely misrepresenting the facts as your figures are out by two orders of magnitude.
