The purpose of this study is to measure the crime level at the administrative dong level and link it with other data related to crime based on the administrative dong to verify which variables affect the change in the crime level, which is a dependent variable.
In the first year of the study, the level of crime in administrative dongs in Seoul and Gyeonggi-do was measured on a scale of 1 to 5 using the safe map managed by the Ministry of the Interior and Safety as described in the research plan. The safe map shows the number of nine major crimes committed over the past three years at the level of the district police station and police box divided into five levels. The Excel data were completed by measuring the crime level of the district police station and police box level recorded in the safe map by graduate students of the master's and doctorate program who participated as research assistants. However, the level of crime measured does not exactly match the administrative dong because the unit of measurement is the district police station and police box. The purpose of this study is to establish criminal data at the administrative dong level. The crime level at the level of the district police station and police box was measured at the level of the legal dong under the jurisdiction of the district police station and police box. Next, the crime level at the administrative dong level was calculated by weighting the crime level at the legal dong level again. Finally, both the crime level at the administrative dong level in Seoul and Gyeonggi-do were measured. Details of this conversion process can be found in the "Spatial Patterns of Crime in Seoul, Korea: An Empirical Analysis at the Administrative Dong Level" in Volume 15, No. 1 of Journal of Korean Criminological Association published as a research result.
In the second-year study, the goal was to collect various statistical data disclosed at the administrative dong level and conduct the study using factors that may affect the crime occurrence level. For the study, data at the level of administrative dongs were collected through the Seoul Open Data Plaza, public data portal, and smart security big data platforms in addition to requests for information disclosure. Data collected from the Seoul Open Data Plaza and the Public Data Portal include population density, gender ratio, foreigner ratio, poverty ratio, early-divorce rate, population mobility rate, number of liquor store, CCTV installation number, race/ethnic differentiation index, etc. On the National Police Agency's smart security big data platform, data such as police station-level safety perception, the number of police personnel, and the five major crime rates could be obtained. In addition, GIS data on frequent traffic accidents in Seoul and Gyeonggi-do were secured and combined with the data collected in this study to be used for research. These newly collected data were used as independent variables and control variables, and various spatial regression analysis was conducted using the crime level at the administrative dong level as a dependent variable.
In December 2021, as the second research result of this study, we published a paper titled "Spatial Analysis of Crime at the Administrative Dong Level of Seoul: Using a Spatial Regimes Model that Considers the Heterogeneity Between Gangnam and Gangbuk" in Volume 15, No. 3 of Journal of Korean Criminological Association.
After that, additional research has been conducted and six research papers have been published so far, and various additional studies will be conducted using the constructed data.
In addition, the constructed data will be disclosed to researchers who want to conduct further research in the future.
