Data from surveys representative of the population of the United States were used to investigate 2 aspects of social distance as a measure of prejudice among Hispanics, non-Hispanic Whites, Jews, Asians, and Blacks. The results extended through 2000 a 65-year decline in prejudice. But, contrary to expectations, these groups were, on average, significantly opposed to virtually all other ethnic groups living in their neighborhoods or marrying their close relatives. The findings suggest that the popular hierarchical explanation of social distances with Whites at the top, Jews next, followed by Asians and Hispanics, and Blacks at the bottom is incorrect. A more accurate explanation is proposed.
