I'm not sure. I tried looking up statistics on Eastern Thrace but something that detailed would likely only be found in official Turkish government files or perhaps a reference book citing them. Not all of the Marmara Region is in Europe, so I would have to pick out the appropriate districts within it. In other words, this is like trying to find data from specific counties in a specific US state.
I was just wondering, how many people in the Vatican have to die to get them on this list? Perhaps just giving one person a dirty look might be enough.
Honestly kinda surprised The UK with London didn’t make the list given the large amount of Stabbings and knife violence there and also surprised with France and Paris given some of the large scale Terror attacks that have happened in the last 10 years and the hundreds of loved they’ve respectfully claimed.
