Abstract
The purpose of this research is to examine relationships between spatio-temporal patterns of crimes and neighborhood daily dynamics in Osaka City, Japan. Collections of mails distributed by Osaka Prefectural Police Department were used to understand postal addresses and date of snatch-and-grab crimes. On the other hand, hourly populations within 250m grid were estimated from a new dataset derived from locations of mobile phones. The results indicate that there are significant spatio-temporal variations of crimes within the city. The relations to neighborhood daily dynamics were studied in different approaches.
