I think people don’t realize how empty South American countries are. They are huge countries with small populations.
Argentina is a massive country with roughly the same population as Ukraine, and only sligthly more than California (45m pop.)
Peru has a population of around 32 million, 6m less than Poland and 2m more than Texas.
Chile has 17 million people, the same as the Netherlands, or 2 million less than New York.
Bolivia, Belgium and Ohio have similar populations of 11.5m
Brazil, Nigeria and Pakistan have similar populations of around 210 million.
Guyana and Suriname have population of around 800,000 and 600,000 respectively, comparable countries in population are Montenegro, Malta and Luxembourg.
We sometimes ignore how huge most South American countries are, and how small populations the have.
