The Gender Innovation Lab (GIL) Federation is a World Bank community of practice coordinated by the Gender Group that brings together the Bank’s five regional GILs: Africa (AFR), East Asia and Pacific (EAP), Latin America and the Caribbean (LAC), Middle East and North Africa (MNA), and South Asia (SAR). Together, they are conducting impact evaluations of development interventions to generate evidence and lessons on how to close gender gaps in human capital, earnings, productivity, assets, voice and agency. With over 188 impact evaluations in 66 countries completed to date, the GIL Federation is building the evidence base for governments, development organizations, and the private sector to increase the uptake of effective policies that address the underlying causes of gender inequality.
