Only a few countries have grown entirely based on immigration, Australia, New Zealand, and America among them.
I know what you mean by this, but just a fun fact I want to crowbar in:
Humans settled in Australia around 50-60,000 years ago, North America around 20,000 years ago, but when the East-Polynesians (who would become the Māori) settled in New Zealand, Oxford University was already 200 years old.



I can’t stress enough how much heavy lifting the phrase “among other steps” is doing here.
