Census Bureau spokesman Jack Martin said the use of "Negro" was intended as a term of inclusion.
"Many older African-Americans identified themselves that way, and many still do," he said. "Those who identify themselves as Negroes need to be included."
即使到了五六十年代Negro都还是主流说法,不是禁忌,也许真的有老黑人只认为自己是Negro吧。另外,Black和African American是civil rights activists提出来的,也许真的存在不认同这些叫法的老人吧。
