The comfort picture is also mixed: Jeju leads on safety and pollution-related indicators, while Kocaeli leads on healthcare-related indicators, climate comfort, and commute-related indicators. The better choice depends on whether the reader wants lower monthly pressure, stronger comfort indicators, or a better balance between cost and daily living conditions.

Cost of living comparison

Cost of living is the first filter for many long-stay decisions, but the available indicators do not provide a separate overall cost-of-living comparison for Jeju and Kocaeli.
