Chapter 6 #IBelong Campaign.74 These include pledges to improve qualitative and quantitative data on stateless populations by 34 States. A total of 29 States submitted pledges to conduct quantitative or qualitative studies and nine States committed to include statelessness in upcoming census exercises (see map). In 2019, an Expert Group on Statelessness Statistics made up of experts from national statistical offices and several UN agencies including UNHCR, UNFPA and UN Regional Commissions was established to work on developing and implementing common standards and definitions on statelessness statistics. The group aims to submit international recommendations on statelessness statistics 74 https://www.unhcr.org/ibelong/results-of-the-high-level-segmenton-statelessness/ to the United Nations Statistical Commission by 2022. In parallel, an inter-agency group of international agencies and academic experts is developing statistical and demographic estimation methods to secure valid, reliable and comparable statistics on stateless populations. This work will be instrumental in developing a clearer global picture of statelessness over time. Improved data will in turn strengthen UNHCR’s advocacy work and help realize the overarching Sustainable Development Goal of ‘Leaving no one behind.’ It will also support States’ commitments to provide legal identity for all by 2030 as stipulated in SDG 16.9.75 75 Target 16.9: By 2030, provide legal identity for all, including birth registration.
