This book, aims to provide a general yet comprehensive analysis of South Korea, specifically in terms of its socio-economics and administrative system. This book is the outcome of a ‘knowledge-base’ project that was named “country report.” I began this project in 2019 with a group of researchers to accumulate local knowledge through the lens of public officials of developing countries who are enrolled in the KOICA GMPA program at Seoul National University. I asked international students to write about their countries’ public administration, policy, political, social, and other contemporary issues. Many students worked relentlessly to share their knowledge of their countries, and as a result, we were able to build a preliminary country report series covering more than 26 countries. However, improving the quality of the country reports proved to be a challenge and so I decided it would be beneficial to first write a standard country report on South Korea. This book offers the following merits. First, we have referred to as many social indicators as possible for an objective description of the administrative and policy issues. Based on the database constructed using Statistics Korea, OECD, World Bank, UN, and IMF, we managed to pull out relevant information. Thus, all the information we have gathered and used can be updated anytime if necessary. Second, we prepared a manuscript through a collaboration platform, Google Docs. Our research staff meet regularly, and they revised the manuscript and gave comments then and there. Third, we have made an effort to offer as many references as possible so that readers can refer to them and use them for their further research.
