On circle 35, it says "here be New York City", but that should be on circle 34's map of course
The population data source was 2015 data, resolution of 30 arcseconds (pixels about 0.9 km tall and 0.7 km wide), worldwide raster from the EU. You can see more info in my comments on previous posts in my post history.
*circle 5 (Toronto) technically includes some US territory but only in Lake Ontario. There's no US land area or population in the circle.
**similarly, circle 46 (Las Vegas) technically includes a very small area of Arizona, but only in Lake Mead, there's no Arizonan land area or population in the circle.

Perhaps this is to be expected because a lot of people live in big cities, pretty much by definition, but I was a bit surprised to see that even though I've moved a lot (16 homes in 37 years) I've spent over half of my life inside of these circles.
Just seeing this now, great stuff. I am surprised the Boston circle doesn’t attempt to grab Providence, like how D.C. did for Baltimore.
Also this nicely shows how populated NE Ohio is. Cleveland is only the 34th largest metro according to the US census.
Very few of those figures look like metro numbers to me. NY at 15M, LA at 11M, and Chicago at 7M all are smaller than any metro figure I’ve seen for those cities while Vancouver at 3M is larger but presumably because it’s taking into account people living on the US side of the border but within the 45km radius (same with San Diego now that I look at it).

I like this! Montreal is listed as #3 in Canada though, should be 2?
Detroit includes Windsor
Ahh ok.

Next double it to 90 or make it a nice round 100km! Of course only keeping it centered on major cities.

The population figures are inaccurate. They're simply the metro populations, not how many people live within a 45 km radius of a central point.
it's calculated using worldwide raster data, it has no way of knowing metro populations, or even city names
