This study examines Korean Americans' perceived incivilities, perceived crime risk, and fear of crime using an explanatory model combining group threat theory of racial hostility and risk interpretation theory of fear of crime. In particular, our hierarchical linear models show strong effects on fear of crime for English proficiency, length of U.S. residence, preference for ethnic Korean media, perceived risk of future black rioting, and anti-black prejudice. We discuss the importance of cultural factors and the dynamics of race and ethnic conflicts in explaining fear of crime, and suggest directions for future research on race relations, perceived victimization risks, and fear of crime.
