“We’re still here,” the narrator says.
“But I think the world is much larger.”
In the late 1800s, millions of Americans migrated across the Atlantic from Canada, and by the 1920s, the world’s population had more than doubled.
It reached 1.3 billion in the late 19th century.
Today, the United States has a population of about 2.2 billion.
It’s the largest country in the world.
In the years since the United Nations population body began keeping track, the global population has steadily risen.
According to the United Nation, the population of the world has increased by more than 6 billion people since 1950.
That’s an increase of nearly a third.
And it’s only getting bigger.
This is the story of how that migration happened.
