After years of research leading up to last year's count, the bureau proposed combining the separate questions about Hispanic or Latino origins and race into one.
And under that combined question, the list of checkboxes would include "Hispanic, Latino, or Spanish" (as well as "Middle Eastern or North African," or MENA) among the major racial groups designated by the White House's Office of Management and Budget, which sets the standards for how the bureau and other federal agencies collect data on race and ethnicity.
That change, the bureau's research found, would have decreased the share of Latinos who chose "Some other race" as their category while making no significant shifts in the share of Latinx people who also identify with "Black" or "White." (Adding a MENA category would have also lowered the shares of people identifying as "Some other race.")
But what the bureau concluded was the "optimal" way of collecting data required approval by OMB. When asking people to self-identify, OMB currently requires a question about Hispanic or Latino identity, which OMB considers an ethnicity and not a race, to be asked before a question about a person's racial identity.
During former President Donald Trump's administration, OMB made no public decision on proposed changes to its standards.
"At the end of the day, the No. 1 faction that was against the combined question was the Trump administration," Mora says.
Asked by NPR how concerned the bureau is now that "Some other race" is the country's second-largest racial category, Nicholas Jones, the bureau's director and senior adviser of race and ethnic research and outreach, said they're "not surprised by the findings."
"While the Census Bureau tested an alternative question design in 2015, we must ultimately follow the 1997 OMB standards and use two separate questions to collect data on race and on ethnicity," Jones pointed out during a press conference in August. "Our testing, however, did show that we could make improvements to the 2020 census race and ethnicity questions within the OMB guidelines."
The Biden administration's OMB has told NPR it's still reviewing those proposed changes to the government's standards and whether they help gather "the data necessary to inform our ambitious equity agenda."
There could be changes in time for the 2030 census
As the bureau ramps up its planning for the 2030 census, some researchers are calling for the federal government to consider adding a different kind of race question, including Nancy López, a sociologist at the University of New Mexico whose research has focused on people's "street race," or what they think strangers assume their race to be.
"Not every Latino is a brown-skinned Latino. There are white Latinos, there are Black Latinos like myself, and there are Latinos who are also street-race Asian," says López, who adds she's concerned about the limitations of data about how people self-identify. "What would be the civil rights use of that data when we recognize that most people are being racialized by others when they seek housing or vote or seek employment?"
