Race and Ethnicity:
The White population remained the largest race or ethnicity group in the United States, yet, the White alone population decreased by 8.6% since 2010.
The Two or More Races population (also referred to as the Multiracial population) has changed considerably since 2010.
The “in combination” multiracial populations for all race groups accounted for most of the overall changes in each racial category.
