Demographic exploration within sustainable local development is pivotal for understanding associative entities in a specific region. This study delves into Romania's demographic views, with a focal point on Local Action Groups (LAGs) in Central Dobrogea. Associative entities encompass political parties, non-governmental associations, agricultural cooperatives, and LAGs, serving as catalysts for positive change, policy influence, and community resilience. This research analyzes 177 respondents' data using SPSS, finding no significant associations between age/gender and participation in associative entities.The work emphasizes the potential influence of demographic characteristics, particularly age and gender, on individuals' perceptions, priorities, and participation in these entities. Age shapes perceptions of socio-economic issues, while gender influences perspectives within the context of sustainable local development. Consequently, this study provides insights into the demographic dynamics of associative entity participation, highlighting their enduring relevance in shaping a more sustainable and resilient local community.
