Background: Delayed marriage among Muslim youth is increasingly observed in Indonesia, Spain, and Portugal as a result of economic uncertainty, educational expansion, and changing social values in contemporary society.
Methods: This study used a qualitative comparative approach through systematic literature review and thematic analysis based on peer-reviewed academic sources.
Results: Economic insecurity and prolonged education were identified as the main factors contributing to delayed marriage across the three countries.
Discussion: Despite different socio-cultural backgrounds, the three countries show converging trends toward later marriage influenced by globalization and shifting life priorities.
Conclusion: Islamic education remains relevant in strengthening moral awareness and family preparedness among Muslim youth.
Novelty: This study provides a comparative Islamic education perspective across Muslim-majority and European secular contexts. However, this research is limited to literature-based analysis without direct empirical field data.
