Disaggregated gender statistics are critical for putting the spotlight on inequality and underscoring the need to realise the rights of poor and marginalised women and girls and prioritize them in policy-making processes. The 2030 Agenda pledges to leave no one behind and to ensure progress for all nations and peoples and for all segments of society. To identify those who are left behind, high-quality, timely, and reliable data disaggregated by income, gender, age, race, ethnicity, migratory status, disability, geographic location, and other characteristics are necessary. The Counted and Visible Toolkit provides a compilation of tools and mechanisms drawing on country case studies to produce disaggregated gender statistics using an intersectional lens, creating credible evidence to inform gender-responsive policies.
