Help with geo question

[sherwood3570]

Anybody a geography major here?

What event caused the largest inter-regional migration within the states?

I'm stuck between the civil war, WWII, and the gold rush.

Any ideas?

Edit: Could be the western expansion aswell, but that would align with the gold rush.

The largest level of interregional migration in the United States was caused by what action by the United States government?

From this site. http://www.studystack.com/menu-39420

This would lead me to believe it wouldn't be the gold rush, but since I have nothing better to do I'll see if I can find you an answer.

EDIT: Sorry, I couldn't get any info for you, hopefully someone else will have some prior knowledge of this topic.
