In recent years, air quality has gradually deteriorated, which has affected human behavior patterns, and made air pollution become an important issue. This study took New South Wales, Australia as our study area to define the spatial relationship between air pollution levels and indoor- and outdoor- crimes. By using the Ordinary Least Square (OLS) and Geographically Weighted Regression model (GWR), the Air Quality Index (AQI) and other relevant factors are used to predict the number of crimes. The results show that the areas with severer degree of air pollution tend to have more domestic violence (indoor crimes) but less robberies (outdoor crimes).
