Fascinating game, if you don't mind, what exactly is Uruguay's population? I'm interesting in finding the full potential of immigration as I once gained a city the size of NYC in Chihuahua, a place that looks like this.
Just checked, and they had 3.5 million people as of 1897, with Montevideo slightly outshining NYC at that point. And if you think having a city the size of NYC in Chihuahua is crazy, I had over 200,000 people living in Sitka!
I'll post a full writeup and screenshots once I finish the game. Up to 1916 now, and it looks like the rest will be pretty stable (or at least I've finished all my foreign policy goals).
