That's the other interesting point about graphing by latitude: the very cold countries such as Iceland also have remarkably low death rates.

It is the temperate, winter latitudes that have extremely high death rates.

Here's the graph, you can see for yourself. A very clear trend based on latitude.

I'm not sure why this trend isn't discussed more in the popular media. Seems quite significant, and is very easy to reproduce. Just scrape Google's covid-19 stats and join with a geographic coordinate source. A journalist could do this by hand with an Excel spreadsheet in about half an hour.

If this trend holds up, then as the Northern hemisphere hits summer, the death rates should plummet. On the other hand, in the Southern hemisphere as winter approaches the death rates will go up.
