This study aims to classify spatial living zones in remote island areas of Korea based on accessibility to basic services. Using QGIS-based network analysis and clustering methods, accessibility was measured at both local and regional levels for 321 inhabited islands with available, maritime transport data. Key services—healthcare, education, culture, commerce, and transportation— were used to derive accessibility indicators. Islands were categorized into four types: (1) Inland-connected Island Living Zones with easy land access, (2) Mid-distance individual Zones highly dependent on maritime transport, (3) Independent Island Living Zones with full internal service coverage, and (4) Remote Hub-Island-Connected Living Zones with core-periphery structures between central and surrounding islands. Each type exhibited distinct spatial and functional characteristics in terms of service dependency and geographic distribution. The findings highlight the need for differentiated strategies in service provision and spatial planning. This study provides empirical evidence to support customized policy development for improving quality of life in geographically isolated island regions.
