The classification of Middle Eastern and North African (MENA) responses, such as Lebanese, Moroccan, and Iranian, to the Census Bureau’s question on race adheres to the Federal Register Notice entitled, “Revisions to the Standards for the Classification of Federal Data on Race and Ethnicity” issued on October 30, 1997 by the Office of Management and Budget. Findings from the 2010 Alternative Questionnaire Experiment (AQE) showed that respondents of MENA origin did not consider themselves to be “White” and felt that their race was “Arab” or “Middle Eastern or North African.” Both MENA and non-MENA respondents indicated that there should be a separate category in the race question to represent this population. Since the AQE was conducted, the Census Bureau has been researching and developing a MENA classification to test on the 2015 National Census Test. The Census Bureau received overwhelming support for testing the new category during the Federal Register Notice comment period, which was open from December 2nd, 2014 through February 2nd, 2015. The Census Bureau will continue working with community stakeholders and experts to further develop the MENA classification and improve the MENA code list leading up to the 2020 Census.
