Highly suggest using Citypopulation.de for your Population statistics. It’s the primary city/population/demographic source for most of the related quizzes on jet punk. Almost every featured one and everyone the quizmaster makes uses that source. Almost every single one of those city population statistics you listed in this quiz is incorrect and/or Outdated, And yes that is for metro/urban population I’m talking about. Wikipedia is not always a great source. Especially for stuff like this.
