Want to know more about how women MPs are organizing themselves in parliaments around the world? IPU has launched a new global database on women’s caucuses in parliament to capture such information in one useful place. The database is a unique tool that provides a global, regional and national perspective on how women MPs have succeeded in coming together to tackle issues in ways that transcend their political differences. The database, available in English and French, lists information about 79 women’s caucuses that exist so far in 189 national parliaments, with names, links and contacts to the groups. Different search criteria filters are available to obtain information on countries, regions, dates, structure, composition, agenda and rules. Produced with financial support from USAID, Irish Aid and the Swedish International Development Cooperation Agency (Sida), the database is to be used in conjunction with IPU’s “Guidelines for Women’s Caucuses”. The Guidelines provide a rationale for why caucuses play a decisive role in the development and implementation of laws and policies on important gender issues, as well as practical information on the steps required to set up and run a successful caucus.
