While entitlements are often expressed as universal and linked to the rights citizens should have, young people's access to them is shaped by their social positioning, meaning that whether, and in what sense, they are citizens is pertinent. If citizens have access to universal entitlements, does this position certain young people who do not have such access as "lesser youth" because their entitlements are reduced and citizenship diminished or non-existent? This paper examines whether and how young, separated migrants wanting refuge may be positioned as "lesser youth". It draws on a sample of them and multisector professionals examining qualitative data on accessing health care, sexual exploitation and rebuilding lives. The data suggest that the legislative and institutional framework they face militates against their enjoying the "universal" entitlements of citizens. This reflects their positioning as "lesser youth" excluded from the full rights citizens are entitled to. Such a positioning is in large part underpinned by contested notions of nationhood, belonging and entitlement central to communitarian citizenship but which exclude them. We argue that a meaningful citizenship for these youth requires a contestation of restrictive communitarian ideas and practices in ways forwarding a more inclusive and socially just multicultural UK.
