If I remember correctly, CR had around 5 million people before. End result: Big ass typo and it's supposed to be 11 million. Wouldn't be a first.
Also, nothing against the sudden, as Karst described well - pretty weird - population jump, but it would cause soooooo many possible issues when there's like a sudden 100 mill refugees now. Imagine having refugees outnumber your own people by tens of times in reality, oh boy would this be funny.
I really believe writing it off as typo is the best to do and not waste more time discussing it. CR could easily be ~8 mill themselves, 3 mill refugees.
