While Mexico has made significant progress in increasing women's representation in elected bodies over recent years - making it one of the top OECD countries for female political participation -their access to positions of power within both Houses of Congress remains uneven. There are still gender gaps in access to leadership in the judicial and executive branches of government, too, and in the Federal Public Administration.

It also explores the barriers to women's participation in public life and in senior positions, such as political violence, a culture of long hours and limited work-life balance policies.
