A 1975 exploratory study is used in this investigation of the cognitive maps of class and racial inequalities held by 113 American and 101 English repondents. An Index of Perceived Inequality is constructed from nine items dealing with inequalities, both among classes and between races, of education, occupation, income, respect, and treatment by the police and courts. The index appears reliable and valid, particularly for the United States. For the United States, factor analyses show that perceptions of class inequalities cannot be separated empirically from perceptions of racial inequalities on the basis of their interrelationships. Thus a single dimension can account for the common variation of the nine items. But in England perceptions of class and racial inequalities tend to separate into two distinct, though correlated, clusters. Additionally, for both countries there is support for grouping the items into those dealing with inequality of opportunity and those dealing with inequality of treatment and condition. Finally, compared with the English, Americans perceived more inequality, were more likely to see a growing economic gap between the rich and the poor, saw a larger number of social classes, and were more likely to say that money is the defining criterion of class.
