Building and sustaining political momentum and identifying evidence-based solutions is essential to achieve the 2030 Agenda. With its emphasis on leaving no one behind, population data that is disaggregated by sex and geography is a fundamental requirement for this agenda. However, many countries' official statistics only publish averages that are gender-blind and mask inequalities. As a result, a growing number of international development organizations and UN bodies are urging countries to invest in their civil registration and vital statistics (CRVS) systems. Reliable vital statistics data drawn from civil registration systems are the preferred source of indicators for the Sustainable Development Goals. This project builds on the outcomes of a global meeting convened at IDRC in Ottawa in February 2018, Making the Invisible Visible: CRVS as a basis to meeting the 2030 Gender Agenda. The meeting assessed the status of the field, identified research gaps, and focussed on positioning gender within the global CRVS agenda. A second convening of high-level and technical experts in Ottawa in February 2020 aims to assess progress since 2018 and inspire further global commitments to integrate gender analysis across activities that strengthen CRVS systems. A two-day event will evaluate opportunities and challenges and offer a forum for candid discussion around what is effective and what is not in national and international efforts to ensure that all civil and vital life events are universally registered and disaggregated by sex. Presentations and discussions will focus squarely around the question of what needs to change to strengthen CRVS systems for inclusive development.  A combination of high-level and technical panels will move discussions beyond advocacy to concrete ideas for operationalizing solutions. Panel themes will focus on areas where more knowledge and innovation are needed, such as exploring the gender dimensions around linking national ID management and CRVS systems, and CRVS systems in fragile or vulnerable environments. The event will also support a deep dive into the vital statistics side of CRVS systems and look at how better data governance, open data use, improvements in linking data and statistics to policies and programs, and monitoring results can promote further investments in CRVS systems.
