So then, the significance of the push-pull factor would be that they were the reasons that pushed people out of their native lands and pulled them towards America?

What were some push factors?

What about pull factors?

The pull factors included population growth, agricultural changes, crop failures, industrial revolution, and religious and political turmoil.

The three main pull factors were freedom, economic opportunity, and abundant land.

Right.

Your first sentence is about push, not pull, factors.

Oh. I'm sorry. That was my mistake.

So then, is my answer correct?

They're right -- I hope you understand them.

So then, the significance of the push-pull factor would be that they were the reasons that pushed people out of their native lands and pulled them towards America, is correct?

Yes. I hope you also realize that we're talking about human beings, perhaps some of your ancestors.

My first ancestor here was an orphan so he had no land to inherit in England. One ancestor came from Germany so that he didn't have to be drafted into the army. Two ancestors -- one French and one English came to fight on opposite sides in the American Revolution.

Also remember the horrible potato famine in Ireland that pushed thousands of people out so that the didn't starve to death. In the late 1800s, early 1900s, many emigrated from Italy because of poverty and lack of land there.

The pull factors included what you've said -- a better life for them and their families.
