So in this report the metric was number of deaths in six months or whatever. And if you wanted to compare that with another observation that was over a year then you'd normalise both to deaths/ year or deaths/ month. Or some other unit of time.
Deaths per capita isn't useful without that time element.
Well, of course. Did that need saying?
It was stated in the report that the comparison was with "the same period last year."
What changed was the volume of traffic. And the number of casualties.
