To me this list looks utter nonsense. Apart from the cost, Kobenhavn must be one of the nicest large cities to live in. So, what are the criteria? Living in a war zone would have to be at or close to the top of the list - so why no Ukrainian cities - or Yemeni? Being in a refugee camp is slightly less bad - so why not Cox's Bazaar? And then there must be countless cities afflicted by extreme poverty but I only notice one (Dhaka) which falls into this category.
