Still today the relationship between some ethnic groups and whiteness remains complex. In particular, some Jewish and Arab individuals both self-identify and are considered as part of the White American racial category, but others with the same ancestry feel they are not white nor are they perceived as white by American society. The United States Census Bureau proposed but then withdrew plans to add a new category to classify Middle Eastern and North African peoples in the U.S. Census 2020, owing to a dispute over whether this classification should be considered a white ethnicity or a race. According to Frank Sweet "various sources agree that, on average, people with 12 percent or less admixture appear White to the average American and those with up to 25 percent look ambiguous (with a Mediterranean skin tone)".
