However, there have been few attemps to compare quantitatively the relative importance of these three kinds of prejudice and discrimination. We have analyzed the race, sex and age inequalities shown by the U.S. census statistics using the method of the Equality Index. We compared inequalities in terms of income, education, occupation, and number of weeks worked. The Equality Index summarizes the amount of similarity between the percentage distributions of two groups, such as the aged and non aged, on a given dimensions, such as income or years of education.
We found that age inequality was greater than race and sex inequality in the number of years of education completed and in the number of weeks worked; that is, there was more discrepancy between the aged and non aged in their education and weeks worked, than there was between the whites and nonwhites, and between males and females. However, in terms of occupation, age inequality was less than racial and sex inequality. Age inequality was also greater than racial inequality in terms of income.
When comparisons were made combining two of the factors, the joint effects were generally additive. The combination of all three factors produced the lowest quality in both income and occupation. Changes since 1950 show nonwhites and the aged gaining substantially more equality in income, occupation, and education; while women were barely maintaining their generally inferior status.
The extent to which these inequalities are directly due to racism, sexism, and ageism, as opposed to biological or cohort differences, is difficult to determine. However, it is clear that the relative amounts of race, sex, and age inequality vary depending ono which inequality is being mesured.
