The Impact of Residential Environment on Crime in South Korea

Purpose: This study aims to analyze the impact of residential environments on the incidence of drug-related crimes, while providing comparative insights into violent and sexual offenses across 146 cities and districts in Korea. Recent increases in drug-related offenses necessitate empirical understanding of regional and socioeconomic risk factors. Research design, data, and methodology: This investigation implements multiple regression analysis based on 2023 crime statistics and urban-level indicators, grounded in environmental criminology and social disorganization theory. Variables include population density, proportion of aged housing, number of entertainment venues, park land proportion, and per capita income, classified under social, residential, and economic characteristics. Results: Drug crime rates were positively correlated with population density, entertainment venue density, and income levels, while park availability showed a significant negative relationship. Single-person household ratios and unemployment were more strongly linked to violent and sexual offenses. Notably, nightlife concentration emerged as a consistent predictor across multiple crime types. Conclusions: The results suggest that distinct environmental variables affect each crime category, while shared urban vulnerabilities elevate overall crime risk. This study provides empirical support for integrating urban planning strategies-such as expanding green spaces, promoting community integration, and enforcing zoning controls-into crime prevention frameworks, particularly for drug-related offenses in dense urban areas.
