Abstract
The purpose of this study is to study areas at risk of population extinction in Gyeongsangbuk-do. Data on resident registration population, births, deaths, marriages, etc. from Statistics Korea KOSIS were used. The another purpose was to consider the degree of risk of cities and counties in areas at risk of population extinction in Gyeongsangbuk-do. Gyeongsangbuk-do is one of the regions with the most population loss in the country. Most of the local governments in Gyeongsangbuk-do, excluding Gumi City, are in areas at risk of population extinction. As of 2022, Gunwi.gun (0.08), Uiseong.gun (0.08), Bonghwa.gun, (0.08), Cheongsong.gun (0.09), Cheongdo.gun (0.09), Yeongyang.gun (0.10), Yeongdeok.gun (0.10), Seongju.gun (0.13), with a population extinction index of 0.15 or less. Goryeong.gun (0.13) and Sangju.gun (0.14) will reach the risk of population extinction among local governments in Gyeongsangbuk-do after 40 years (Kim, 2023).
