The study of overseas Koreans is a systematic and empirical scholarly study about overseas Koreans. Because of its comprehensive and multi-disciplinary nature, it requires various research methods and thus an integrated approach that synthesizes qualitative and qualitative methods is desirable. The study of overseas Koreans can be approached from the perspectives of humanities, social sciences, and natural sciences, but in this article I focus on social research methods, especially survey methods, as a useful methodology for the study of overseas Koreans. As I review critically existing literature of overseas Koreans, I find that current research methods have the problems of the low degree of representation of research findings due to the use of non-probability samples, the low level of comparability of research findings, the lack of standardized measurements and indices, the low level of analysis that remains at a level of descriptive statistics, the use of improper question items, and the intervention of a researcher's values in his or her study. To ameliorate these problems, we need to collect scientific and probabilistic samples, conduct comparable inter-country surveys by using the same research tools, develop value-neutral and reliable and valid question items, integrate quantitative and qualitative research methods, and to use reliable secondary data of government and private research institutions of foreign countries.
