Surveys are an important data collection method for national statistics in Korea. As of July 22, 2024, based on data provided by the MDIS of Statistics Korea, approximately 92% of national statistics are compiled using the survey method, and about 85% of these rely primarily on face-to-face interviews for data collection. However, with the increase in single-person households, the nonresponse rate of surveys has been rising each year. This study examined the behaviors of respondents across different survey modes used in the 2020 Korean Crime Victim Survey, whose raw data about survey response modes is available for public use on the MDIS website in Statistics Korea. The results show that, overall, the younger the age group, the higher the proportion of self-administered responses, with this proportion being higher for female than male except over 60 years old. Notably, the 20s age group has a significantly higher percentage of self-administered (TAPI) responses for both male and female. Furthermore, the response using tablets generally has a higher proportion compared to the response using paper across all age groups except for females in their teens, regardless of whether the survey is interviewer-administered or self-administered.
