I'd guess that they're using Eurostat data, but the UK is present, and they stopped participating in Eurostat when they left the EU. So either it's not that, or it's old data.
A bit off-topic, but I kind of wish that the UK and some of the other countries in Europe could participate in some level of voluntary, best-effort participating to share data. Like, okay, if you're not in the EU, you aren't bound to use the same statistical standards that EU members are, but I am pretty sure that some countries do or don't care, and it's kind of obnoxious that it makes it harder to compare datasets spanning all of Europe.
How is this always a comment? Of course, there are a lot more countries in Europe and the world.
I suggest you search for a CSV file and create your own diagram. :)
Or one has to deal with the fact that not every picture includes everything.
Because you're biasing the diagram by deliberately excluding data. You could have excluded the best. Or the worst. Or some in between so two look close together but aren't. Or it could look more uniform than it really is. Excluding data and not being transparent and upfront with is, is skewing things.
Something like All european countries with a population > x
Even that isn't quite it. I mean, Russia's got the largest population in Europe, and it's not in there. Turkey is the second-most-populous country with territory in Europe, though the bulk of that is outside Europe. Ukraine's not in there.
It's like "some but not all of the EU plus some other countries in Europe, like Serbia and the UK". They've got Estonia and Latvia, but not Lithuania, which isn't something that I'd expect to see too often.
Do I need to precise that my post was a /s ? It was ! Actually already 2 comments are saying that US is missing, so I joked about it and about the fact some said this is biased because countries are missing
Actually there is all the source given in the picture itself, if a country is missing, maybe check the data before complaining about people hiding things to you; maybe the data itself does not exists for the country you think is missing
Initially I was like βwow America sucks so much we didnβt even make the listβ. Then I read the rest of the image. Then I noticed the name of this community. Iβm still just going to assume we wouldnt make the list anyway
