- Abstract
- The purpose of this study is to analyze the population imbalance distribution of the resident registration population of Korea in local governments, metropolitan and noncapital regions. This study predicted the future distribution of the proportion of the population of local governments, metropolitan and non-metropolitan areas, compared to the national population for 80 years from December 2020 to 2100. With these prediction results, another purpose of this study is to inform the seriousness of the imbalance in the proportion of the population of local governments and the metropolitan and non-metropolitan areas. After Korea’s population peaked at 51,851,427 in November 2019, a population deadcross occurred. As a result of the impact, Korea’s population decreased by 22,404 for the first time, and Korea’s population reached 51,829,023 in December 2020. The proportion of the population in the metropolitan and nonmetropolitan areas of Korea was around 51% vs. 49% in December 2020. However, the proportion of the population in the metropolitan and non-metropolitan areas is 62.7% vs. 37.3% in 2100, which is a serious gap. This predicts a very biased population distribution of local governments and population imbalances in metropolitan and non-metropolitan areas.
