Dr. Dohyeong Kim, associate professor of public policy and political economy and geospatial information sciences (GIS) in the School of Economic, Political and Policy Sciences, and his co-authors received funding from the Korean Institute of Criminology, a national crime and criminal justice research institute, to support the research.

The study focused on Dongjak-gu in Seoul, a popular area known for its fresh seafood. The district has nearly two and a half times the population density of New York City, with a lot of pedestrian traffic. The Korean government relies heavily on outdoor video cameras to monitor crime.
