Women in Parliament, 1945-2003: Cross-National Dataset (ICPSR 24340)

Principal Investigator(s): Paxton, Pamela, Ohio State University; Green, Jennifer, Luther College; Hughes, Melanie, University of Pittsburgh


This data collection provides information on women's inclusion in parliamentary bodies in over 150 countries from 1945 to 2003. The dataset allows for extensive, large-scale, cross-national investigation of the factors that explain women's attainment of political power over time and provides educators with comprehensive international and historical information on women in a variety of political positions. Information is provided on female suffrage, the first female member of parliament, yearly percentages of women in parliaments, when women reached important representational milestones, such as 10 percent, 20 percent, and 30 percent of a legislature, and when women achieved highly-visible political positions, such as prime minister, president, or head of parliament.
