Recently, 「Special Act on Support for Depopulated Areas」 has been enacted in South Korea. 89 small cities that are in danger of extinction due to population decrease have been designated as depopulation area for intensive support from the federal government. The purpose of this research was to find the answer on how depopulation area designated can be manage their funds to induce young people. In this regard, this study examines the relationship between variation in local-level spending and population influx in the age ranging between 20 and 39 with depopulation cities located within Daegu, Busan, Gyeongsangnam-do, Gyengsangbook-do. The statistically significant evidence indicates that cities that spent more Economic Development-related funds Social Welfare-related funds led to more population influx aged 20 to 39. Otherwise this research has shown that more expenditure in General Administration section did indeed decrease levels of influx of young adult population aged 20-30. This evidence suggests that how well the financial expenditure related to Economic Development funds and Social Welfare funds are implemented, the new young population aged 20-39 successfully will be entered within the cities experienced population decline. This finding can be very informative for local governments with depopulation of rural areas.
