Chapter 1 begins by presenting an overview of the vicissitudes of descriptive representation in state legislatures for women and men from the four largest racial groups in the United States, from 1996 to 2015. The chapter then previews the book’s main finding: factors related to representation and candidate emergence, such as the relationship between district populations and descriptive representatives or political ambition, are shaped by race and gender simultaneously. To account for the persistence of underrepresentation among women and minorities, Chapter 1 then advances the intersectional model of electoral opportunity. The model accounts for external and internal, multilevel pressures that constrain and facilitate the realistic candidacy opportunities for white women, white men, men of color, and women of color. The chapter closes by discussing the necessity of studying Asian American women and men, and Latinas and Latinos, in order to better understand representation in a nation shaped by immigration and immigrant communities.
