The 2030 Agenda for Sustainable Development, which promises to “leave no one behind”, recognizes both international migration and gender equality as integral to sustainable development. For the Sustainable Development Goals (SDGs) to be realized, there is a need to strengthen national-level statistical systems for collecting, analysing and using gender-disaggregated data to inform gender-responsive migration governance. Not having evidence-based, gender-responsive migration policies hinders global efforts towards gender equality, and it limits the potential to maximize benefits from migration for development, including its contribution to the realization of the SDGs.
