How did the Great Migration of African Americans to the North affect the Roaring twenties and great depression?

[Mason]

For my english report, i have to choose a topic for writing a paper on effects that certain events had on The Roaring Twenties and The Great Depression. I'm most likely going to choose The Great Migrations of african americans to the north, but I don't quite know how this impacted the time period of the roaring twenties and the great depression, and that's the whole entire point of my research paper?
Any ideas on how the great migration affected the roaring twenties and the great depression time period?
