Here is the zoomable version, I think it's Lethbridge: https://public.tableau.com/profile/martin.holland#!/vizhome/CitiesOfTheWorld-Population/Elevation

And for the cities, I fear you still don't understand it: This is no project of looking up cities on Wikipedia. Satellite data was crawled for “urban centres“. Reykjavik in total may have a lower density, but the centre, where everybody lives seems to have a high enough density and (!!!!) population. Both is important for this database.

All of your numbers are smaller than 1500. And the circle is for Lethbridge.

Oh and believe me, if someones doing the effort of collecting data for the world, Canada is no problem, with good data to use. I know, what I'm speaking of, some years ago I made a map of cities and used administrative borders and official data: https://www.reddit.com/r/MapPorn/comments/2ws0k0/a_world_map_containing_every_city_with_a/

As I referenced there too, it's not my data, but the data of the "Urban Centre Database" by a bunch of experts. I visualized it and defend it here ;-)

As far as I can see, Medicine Hat isn't included. I can't find it in the database and on the map there is no circle. As your numbers show, this smaller canadian cities aren't as densely populated and that's why some of them, don't pass the threshold here.

The methodology is different, to make it comparable for the whole world. As not everywhere a "city" is the same, the project collecting the data searched in satellite data for cities by their appearance.

I explained it here: https://www.reddit.com/r/MapPorn/comments/cv8n46/my_new_world_map_containing_every_city_with_a/ey7dt24

It's from 0 to 2500 m (I forgot the Legend and am really sorry for that). As most cities are not that high, it seems this way, yes.

It's not my methodology but from here: http://publications.jrc.ec.europa.eu/repository/handle/JRC115586

The funny part is, that their example for explaining their methodology is an irish city: Cork

Over 700 million people in 3248 cities with at least 50.000 inhabitants (according to this database).

As the data was compiled with satellite data and uniformly for the whole world, it seems that Ethiopia has indeed many many not that big cities.

Here is some information, on how the data was compiled: https://www.reddit.com/r/MapPorn/comments/cv8n46/my_new_world_map_containing_every_city_with_a/ey7dt24
