For the 2020 census, the U.S. Census Bureau is changing how it will ask black people to designate their race. Under the check box for "Black or African American," the bureau is adding a new space on the census questionnaire for participants to write in their non-Hispanic origins, according to a recent memo from the head of the 2020 census. "African American," "Jamaican" and "Nigerian" are listed as examples of origins on a questionnaire the bureau is testing for 2020. The change means many black people in the U.S. may have to take a closer look at their family trees to answer what can be a thorny question: Where are you really from? While many black immigrants can cite ties to a specific country, that question is difficult, if not impossible, for many U.S.-born African-Americans to answer. The bureau has not responded to NPR's questions about why it is making this change to both the "Black" category and the "White" category," which will also include a new write-in area for origins.
