This chapter explores how Mexico can meet those challenges and the steps it can take to close remaining gender gaps in top public decision-making positions. Whereas women accounted for only 22.6% of members of parliament in the Camara de Diputados (Chamber of Deputies) in 2005, they currently hold 42.37% of the 500 seats. In the Camara de Senadores (Senate) they occupy 33.6% of the 128 seats, compared to 17.19% in 2006. Such representation is well above the OECD average of 28.47% of seats in lower houses and unicameral legislatures.
