This study examines women's policy agencies (WPAs) in Mexico at the sub-national level using four structural variables that the literature has identified as critical: location within the government, mandates, administrative capabilities and leadership. I provide a descriptive inference based on original budget data, human resources and sub-national legislation (2007 to 2014). The data confirm that cross-sectoral mandates may be difficult to fulfill in weak bureaucracies, which supports the proposal that a better strategy might be to build institutions that have a focused mandate. Finally, the Mexican case supports the notion that creating a WPA with a broad mandate and high administrative status that is underfunded may be a low-cost act of legitimacy for governments.
