Uruguya ratified the Convention on the Elimination of All Forms of Discrimination against Women (CEDAW) in 1981.

However, under a 2009 quota law, women must comprise one-third of a party's candidate list beginning in 2014. Women make up approximately 25 percent Uruguay's armed forces, compared to an average of 4 percent in Latin American countries. A widespread array of community organizations are active in civic life. Numerous women's rights groups focus on problems such as violence against women and societal discrimination.
