If the United States became a “majority-minority” nation,

there would be more ethnic minorities in the population than whites.

Explanation:

A majority-minority region refers to a term used for a division in which social, racial, or ethnic minorities form a majority of the total local population. And therefore less than half of the total population are represented by the dominant group which is the population of the Non-Hispanic white population in the case of the United States. Clearly, the rise in the population of ethnic minorities as compared to the other white Non-Hispanic people in the U.S would lead to making it a majority-minority nation.
