This study examines housing insecurity among young people classified as NEET (Not in Employment, Education, or Training) in the Trnava region in Slovakia, placing their experiences in the context of post-socialist housing transformations. Drawing on the Social Affective Citizenship (SAC) framework, we interpret the Slovak housing system as an ecosystem of formal and informal, state, market, and community arrangements that simultaneously distribute material resources and affective signals of recognition, dignity, and security. Based on 108 qualitative interviews with NEETs and professionals, the analysis shows that unstable housing, uncertain income, and the absence of social support are key mechanisms that reproduce social exclusion. A typology of existential and housing deprivation identifies the most vulnerable subgroups. The study examines concepts such as affective governance and political empathy and demonstrates how current housing policy creates an affective regime that often selectively favours groups that meet expected social norms, while NEET youth are largely excluded from the focus of policy. The findings show that stable and dignified housing is a prerequisite for meaningful participation in work, education, and independent adult life, and call for the integration of political empathy and supported housing into housing policy as tools to strengthen the social affective citizenship of NEET youth. By linking housing sociology with the Social-Affective Citizenship framework, the study addresses an underexplored gap in NEET research: the role of housing insecurity not only as material deprivation, but also as a mechanism of affective exclusion and selective political recognition in post-socialist welfare systems.
