This chapter discusses the intersectionality and deals with research findings on intersectionality including gendered race, intersectional invisibility, and double jeopardy. It describes the historic origins of intersectionality with respect to Black women and provides the difference between intersectionality and faultlines. The chapter focuses on different characteristics that can intersect, including social class, religion, and sexual orientation, among others. The intersection of race and gender has received most attention in intersectionality research, probably because more research has been conducted about race and gender than any other characteristics. Double jeopardy represents the intersection of race and sex and the disadvantages that women of color can face because of their sex and racial/ethnic group membership. Faultlines are similar to intersectionality in that they both consider multiple attributes on which people could be distinguished at the same time. Only a few research papers have measured sex and race at the same time, thereby allowing us to glean information about intersectionality with respect to discrimination.
