ORLANDO, Fla. (AP) — For the first time in 27 years, the U.S. government is changing how it categorizes people by race and ethnicity, an effort that federal officials believe will more accurately count residents who identify as Hispanic and of Middle Eastern and North African heritage.

The revisions to the minimum categories on race and ethnicity, announced Thursday by the Office of Management and Budget, are the latest effort to label and define the people of the United States.

“You can’t underestimate the emotional impact this has on people,” said Meeta Anand, senior director for Census & Data Equity at The Leadership Conference on Civil and Human Rights.

The changes also strike from federal forms the words “Negro” and “Far East,” now widely regarded as pejorative, as well as the terms “majority” and “minority,” because they fail to reflect the nation’s complex racial and ethnic diversity, some officials say.

Grouping together people of different backgrounds into a single race and ethnicity category, such as Japanese and Filipino in the Asian classification, often masks disparities in income or health, and advocates argued having the detailed data will allow the information about the subgroups to be separated out in a process called disaggregation.

But the revisions have long-term implications for legislative redistricting, civil rights laws, health statistics, and possibly even politics as the number of people categorized as white is reduced.
