1.7 Sampling framework Study populations As elaborated in Section 1.5, eight groups of stateless persons were identified to be prioritised for in-depth interviews as a main goal of this study was to understand the lived experiences of stateless people. However, other relevant stakeholders were also interviewed, as described below. The questions utilised in all of the interviews can be found at https://osf.io/kvf5s/. 1. 2. 3. Individuals from the eight stateless populations: The first category comprises individuals from the eight stateless populations. The interviews focused on their lived experiences as stateless persons in order to understand the issues they face in the denial of their right to nationality and its impact on other human rights, particularly economic, social, and cultural rights, as well as the impact of the COVID-19 pandemic on stateless individuals. Civil society organisation workers working with one of the eight stateless populations: Semi-structured interviews were also conducted with humanitarian agencies and civil society organisations (CSOs) that work with one of the eight stateless populations. These interviews focused on the advocacy work and experiences of the CSOs or humanitarian agencies in assisting and working with stateless populations with regard to their right to nationality, as well as any challenges in assisting stateless individuals during the Covid-19 pandemic. In some cases, they may function as proxies for certain stateless populations through case management data. Representatives from government agencies or stakeholders working with one of the eight stateless populations: Semi-structured interviews were also conducted with relevant government agencies or stakeholders that work on matters that affect any of the eight stateless populations. These interviews focused on the roles of relevant government agencies and stakeholders in facilitating the acquisition of citizenship for stateless populations and how existing government policies align with laws on citizenship, adoption, immigration, and equality. 15
