Jeong, Ye-Eun, Kim, Seung-Rae, Choi, Min-Gyeong, Shin, Eun-Jee, Kim, Dong-Wan, & Cho, Tae-Rin. (2023). “Refining Social Strata Variables in Korean Sociolinguistic Variation Research”. The Sociolinguistic Journal of Korea, 31(4), 33-69. This paper critically assesses existing studies on Korean language variation by social strata, proposing alternative approaches to address issues related to these variables. Previous researches have involved papers hierarchically categorizing social strata variables based on common perceptions or assigning weights to them arbitrarily. However, the impact of social strata variables and their weights on language variation remains unknown without thorough data collection and statistical analysis. Consequently, we emphasize the need for a more comprehensive presentation of social strata variables through an interdisciplinary approach taking into account sociological, economic, and political foundations, and stress the necessity of statistical test, observing the influence of each variable on linguistic forms through regression models
