What two migration patterns have changed population?

* The Great Migration: This migration of African Americans from the rural South to the urban North and West occurred in the early 20th century. It was driven by a variety of factors, including discrimination, poverty, and the desire for better jobs. The Great Migration had a profound impact on the U.S. population and culture, and it continues to shape American life today.

* The Latin American Boom: This migration of people from Latin America to the U.S. began in the 1960s and has continued to the present day. It is driven by a variety of factors, including poverty, political instability, and natural disasters. The Latin American Boom has had a significant impact on the U.S. population and culture, and it is expected to continue to grow in the coming decades.
