Previous research has suggested that men are more engaged as citizens than are women. Yet, little is known about gender cleavages across a variety of citizenship norms. To what extent do men and women define citizenship differently? To address that question, this study examines the importance men and women assign various citizenship rights and responsibilities using 2004 ISSP data from 18 Western, industrialized nations. Using a disaggregated approach to understanding definitions of citizenship, we examine political, civil, and social rights and responsibilities. After controlling for a variety of demographic and attitudinal influences, we find that men and women are not different in their views regarding the importance of political responsibilities. However, women do view political rights as significantly more important than do men. Further, in comparison to men, women view both civil and social responsibilities and rights domains as significantly more important.
