Declining response rates and resulting increases in costs for face-to-face surveys are common worldwide. Therefore, there is a need to refine mixed-mode surveys, which are considered the most suitable survey method for the current survey environment. This study aimed to identify the characteristics of respondents who choose survey modes from the 2024 Social Survey of Statistics Korea, and identify ways to improve survey efficiency, reduce nonresponse rates and survey costs. We used gender, age, number of household members, housing type, and education level as explanatory variables to identify groups that prefer specific survey modes. As a result, when looking at it by age group, both men and women in their 60s and older preferred the face-to-face interview, while the remaining groups preferred the non-face-to-face methods (self-administered or internet). By household size and age group, the following groups, both men and women, preferred the face-to-face interview : single-person households aged 50 and older; single- or two- person households aged 60 and older, and those aged 70 and older regardless of household size. The preference for the face-to-face interview among single-person female teens was particularly noteworthy. By gender, education level, and age group, both men and women aged 70 and over, regardless of educational background, preferred the face-to-face interview. Those aged 60 and over with a high school diploma or lower, and those aged 40 to 50 with a middle school diploma or lower, preferred the face-to-face interview. By education level and household size, those with a college degree or higher and those with three or more household members preferred the non-face-to-face methods.
