Which city in Unova has the highest population, Nimbasa city or Castelia city ?

Question

i wanted to confirm that nimbasa city has more population or castelia city. when I played the game, castelia streets had thousands of crowds or people going and coming. but when I reached the stadiums in nimbasa city and thought that an average stadium could hold up to a few ten thousand fans with two of them. though size-wise castelia wins but I need quantity.

Answer 1

According to Bulbapedia, Nimbasa has a population of 150, or 239 counting all the trainers in the stadiums. Castelia City has 127.

Note that's only the characters that are actually visible in the game. In reality you can't go into every single room in every single building in the cities. Given that Castelia has many skyscrapers the real population would be much higher. Also the people in the Nimbasa stadiums would likely live somewhere else and travel there to watch games.
