WASHINGTON (AP) — After more than a century, the Census Bureau is dropping its use of the word "Negro" to describe black Americans in surveys.

Instead of the term that came into use during the Jim Crow era of racial segregation, census forms will use the more modern labels "black" or "African-American".

The change will take effect next year when the Census Bureau distributes its annual American Community Survey to more than 3.5 million U.S. households, Nicholas Jones, chief of the bureau's racial statistics branch, said in an interview.
