The object of this study is daycare centers, home long care institutions, and medical clinics shown in 2022 small residential zone population data, which was statistically analyzed by small residential zone types. The conclusions of this paper are as follows: Firstly, population based on Jeju-si and Seogwipo-si original downtown is continuously decreasing, while the concentration of population is shown in regions where new housing sites were supplied, Nohyung-dong, Ido 2-dong, Yeondong, Aradong residential zone, and commercial concentrated areas in Seopwipo, Seoheungdong and Dongheungdong residential zone, Secondly, an analysis of essential living facilities indicates that while daycare centers are generally well-distributed across many residential zones, distribution of home long-term care institutions and especially medical clinics is uneven, which is required to be improved. Fourth, when analyzing a type-based analysis, Type 1 has an adequate supply of daycare centers and home long-term care institutions, as well as a sufficient number of clinics. Type 2 has sufficient daycare centers and home long-term care institutions, but there is an oversupply of clinics. Type 3 has a good supply of daycare centers and home long-term care institutions, but there is a need for more clinics. Type 4 has an adequate supply of daycare centers but is severely lacking in home long-term care institutions and clinics. Type 5 has sufficient daycare centers and home long-term care institutions but lacks clinics, indicating a need for additional clinic facilities.
