Collective efficacy, defined as the combination of social cohesion and informal social control, is a key concept in criminology; however, research findings in Korea remain inconsistent. While prior studies often aggregate these components into a single score, Twigg et al. (2010) argue that this approach may obscure critical distinctions. This study explores distinct patterns of collective efficacy in Korea, focusing on unbalanced combinations and their temporal stability. Using six waves of data (2012–2022) from the National Crime Victimization Survey, Latent Profile Analysis (LPA) consistently identified four latent groups: High-High (balanced high), Average, Low-Low, and Low-High (low social cohesion but high informal social control). Subsequent ANOVA and Chi-square revealed that the High-High and Low-High groups exhibited the most contrasting demographic and residential characteristics. These findings confirm the Low-High type as a stable phenomenon in Korean society, highlighting the limitations of unidimensional measurements and underscoring the necessity of analyzing the two components separately.
