The authors explored self-reported experiences of interpersonal sexist discrimination and responses to such incidents in a heterogeneous sample of 262 women in the northeastern United States. They divided the sample into 2 categories for age (< 30 years, > 30 years) and for ethnicity (women of color, European American women). Across categories of age and ethnicity, the participants (a) commonly experienced sexist discrimination and (b) viewed men as the primary perpetrators of the discrimination. Although the women's reports of sexist experiences were similar for the most part, the authors found significant age differences in the frequency of categories of sexist events and in specific events, as well as in some general responses to such incidents. Ethnicity, operationalized here as women of color and European American women, did not have a significant influence.
