The purpose of this study is to suggest ways to utilize increasing immigrants to Jeju as a growth engine for local development at a time when a low birth rate and becoming an aging society are emerging as serious social problems. For this purpose, we reviewed the current conditions of people' s moving in and out of Jeju Island and analyzed immigrants opinions on settling in Jeju. Based on these reviews and analysis, we suggest ideas of short-term and long-term projects to enhance the satisfactory levels of settlers. Policy of attracting migration to Jeju is very important and also in line with establishing a free international city which Jeju Special Self-governing Province has aimed for. In order to maintain the influx of the population continuously, it is needed to have concrete and lasting pIans which reflect various types, timing and length of migration.
