Who Is Multiracial?

The size of the multiracial population depends on how questions about race are asked, reports Pew Research Center. In a test of how different questions produce different results, Pew surveyed a nationally representative sample of adults and found the following...

Standard two-questions: This is the methodology currently used in the decennial census, Current Population Survey, and American Community Survey. Respondents are first asked to select their race(s), then they are asked about Hispanic origin. Result: 3.7 percent of the population is multiracial.

Single question with Hispanic as an option: This single race-or-origin question is being considered for the 2020 census, replacing the above methodology. Respondents are asked to select their race or origin, with Hispanic as one of the choices. Result: 4.8 percent of the population is multiracial (not including Hispanic responses).

Family history questions: Respondents are asked not only about their own race but also the race of their parents and grandparents. Result: 6.9 percent of the population is multiracial. When respondents are asked about the race of great-grandparents and earlier ancestors, the multiracial share rises to 13.1 percent.
