Social Representations of Regional Sustainability and Youth Mobility in South Korea: A Q-Methodological Approach to Local Extinction

This study examined the critical sustainability challenge of regional demographic decline in South Korea by analyzing how young people’s mobility decisions are intricately influenced by structurally and socially constructed meaning systems. Countering strictly economic deterministic views, this research posited that youth out-migration is a complex socio-cognitive process mediated by social representations of place—collectively constructed and circulated meanings attached to regions. Applying a secondary analysis of Q-sort data from 24 undergraduate students at a regional national university, the study integrated Q methodology with Social Representation Theory to systematically identify youth typologies regarding regional identity, territorial stigma, and local extinction. Participants sorted 44 statements encompassing place attachment, local consumption, cultural experiences, and policy effectiveness. Rigorous factor analysis revealed four distinct perception typologies: identity-based strategic mobility, conditional leaving based on internalized success norms, re-anchoring toward alternative lifestyles, and skeptical leaving rooted in profound institutional distrust. The findings empirically demonstrated that identical structural constraints can produce highly divergent mobility trajectories—ranging from active retention to complete resignation—depending entirely on the region’s socio-cognitive representation. This study demonstrates that local extinction is not merely a demographic condition, but a socially constructed framework of meaning and an object of social representation that shapes youth perception typologies and mobility judgments. Accordingly, moving beyond conventional technical interventions, meaning governance, and strategic communication are needed to help reimagine regional futures.
