Men from majority racial, ethnic, and religious groups continue to dominate electoral politics in most countries. At the same time, national legislatures are becoming more diverse. Cross-national research on inequality in national politics focuses most often on women, but occasionally addresses the political representation of other marginalized groups. This review brings together these distinct areas of research – cross-national studies on the representation of women and minority groups in national legislatures – to think about diversity in politics in a broader way. Such an approach suggests future studies should: (i) acknowledge important differences among women; (ii) focus on more than one type of minority group at a time; and (iii) explicitly examine variation in the overrepresentation of majority men as political elites.
