In this Annual Report, we discuss many concrete examples of how the work of the GDP over the past year has had an impact. We discuss, for instance, the growing use of the GDP’s online database the Global Immigration Detention Observatory, and the role it has played in calls for change. We highlight how UN human rights mechanisms have made calls to action reflecting our recommendations while media outlets across the globe have made use of our information to bring public attention to the plight of detainees. We feature cases where the GDP website has helped connect families with detainees. And we reflect on how our interactions with academics, NGOs, government officials, and international organisations have helped build new consensus on reforming detention institutions.
