Were people of mixed racial or ethnic heritage be able to identify themselves on the form?
Yes. In October 1997 the Office of Management and Budget (OMB) issued revised federal standards for collecting and presenting data on race and ethnicity. Among other changes, the standards allow respondents when answering the race question option to “mark or select one or more races.” The OMB made this modification after considering recommendations from its Interagency Committee for the Review of Racial and Ethnic Standards, information obtained through public hearings and other sources of public opinion, and test results from the Census Bureau and other federal agencies.
