Maybe this clarifies for others: there's no City south of Tokyo with a population bigger than Tokyo. Tokyo and Seoul are the only cities south of NY that have larger populations. And etc.
I was curious about Alert's name, and assumed it was because the town served as an alerting system for something, but I looked it up and turns out it's cause a ship called HMS Alert wintered there.
Maybe I'm misunderstanding something, but those population numbers seem very wrong. Last I checked, NYC only had about 8.4 million people and Tokyo only 13.9. Does this include the surrounding suburbs?
Yes. This map says "human settlements", not "population counts within city limits". There are various ways to define the borders of an urban settlement, and the numbers represented seem to align with the figures under "urban area" in this list, which is defined within and pulled from this report.
The numbers are close to, but not quite, what Wikipedia has. They’re using 2018 UN estimates, which includes the entire metro area, not just the city proper. I’m assuming OP is using a more recent version of this data, as it’s at least 5 years old at this point.
No clue about Japanese cities, but if you search for an American city's population you'll get the metropolitan population, not the greater city's population. That's how, according to Wikipedia, Sydney has a similar population to LA, despite LA having 10x the population density. If you include the suburbs LA is an order of magnitude larger than Sydney.
Similar with any UK city other than London and a few small ones, it makes it easy to spot mapmakers who've used the metro/borough population based on whether they include Manchester (borough 550k, metro 2.72M), Birmingham (borough 1.15M, metro 2.59M) on their maps... I've also seen some include Liverpool though (looking at you hoi4) when it's smaller than both in all metrics
East and west work fine if you use either the international date line or 180 degrees as the "edge." Tbh tho, east probs wouldn't be too interesting, it would just be Tokyo, maybe another coastal asian city, and some islands
It's a military base. Russian bombers and ICBMs would fly over Alert in order to attack Toronto, therefore someone has to be there. The Arctic is also a contentious area for oil and gas exploration and as a way to bypass the Suez and Panama canals
I'm confused about what this map is actually saying. This is basically just the max population city on any given long. But that's the other thing, what's the east west cutoff? There's multiple settlements from Russia, so it's not per country. Lots of those settlements are much closer together to each other than say, new York and Seattle or LA or whatever it would end up being. What's the margin of degrees on east west?
Best I can tell, the data set must have been "we picked some random recognizable and unheard of settlements and called it good."
Also the geographic north pole isn't marked on the map, which adds to the confusion. The lat/long don't even go to the north pole, or anywhere close to it! That's arguably the most important reference point of the axes...
Maybe someone who understands the map better can explain it better, but from the information I can see it makes no sense and doesn't seem to tell me anything.
They're all smaller* than the next northernmost on the chart.
Tokyo is 35 North and new York is 40 North - there's no European city larger than new York between those latitudes.
Next is new York (40 North) and Moscow (55 North). There's no European city that is larger than Moscow between those bounds.
But it depends on what you define as the boundary of the settlement for population purposes. You might include Istanbul (41 North) there if you define population differently. This list has Istanbul in front of Moscow population wise.
Helsinki should be on the chart though as it has a greatdr population than Arkhangelsk (674,963) and lies further north than Saint Petersburgh (60° 10′ 15″ N, SP: 59° 56′ 15″ N)
