The Census just released shows that Hispanic/Latino persons who identified themselves as “two or more races” rose from 3 million in 2010 to 20.3 million in 2020. Non-Hispanic/Latino persons (such as white, Black, Asian) who identified themselves as two or more races rose from 6 million to 13.5 million.
These self-identified multiracial persons were 3% of the total population in 2010. In 2020 they were 10% of the population.
