This research investigates the interplay between public administration, educational socialization on social media, population literacy awareness, and public satisfaction in the context of population services. The primary objective is understanding how these variables are interconnected and their collective impact on public satisfaction. The study employs a quantitative approach, collecting data through structured questionnaires from a randomly selected sample. Data analysis involves various statistical techniques using Smart PLS, including regression and mediation analysis. The findings reveal that public administration significantly influences population literacy awareness, underscoring the role of government agencies in shaping citizen understanding of demographic policies. While it was anticipated that population literacy awareness would mediate the relationship between public administration and educational socialization on social media for public satisfaction, this mediating effect needed to be supported. However, social media use was found to influence population literacy awareness, indirectly affecting public satisfaction directly. It highlights the potential of digital platforms to enhance citizen understanding and engagement. The implications are substantial. Governments should recognize the importance of effective communication and digital engagement in fostering an informed and satisfied citizenry. Additionally, tailored communication and education initiatives are crucial for promoting public understanding and engagement, ultimately contributing to higher levels of public satisfaction. The research's novelty lies in its exploration of the complex dynamics among these variables and its focus on the role of digital platforms in enhancing population literacy awareness. However, some limitations include the potential for context-specific findings and the need for further research in diverse settings.
