Seasons of Crime in London

This paper investigates whether different types of crime share common traits in their seasonal fluctuation. Specifically, we examine the similarity and difference in the patterns of their trend, the amplitude of the seasonal fluctuation and the peak and the trough seasons to see whether they share common underlying factors. Results show that most seasonal crimes peak in the summer, while some had non-seasonal fluctuation; regardless of the amplitude of their fluctuation. Principal component analysis suggests the presence of the intensity of the seasonality of crime, and reflection of the peak season of the respective crime.
