Information and communication technologies have gained further importance due to digitalisation in many areas including tourism and security. This chapter aims to analyse interrelationships between tourist arrivals, crime rates, and internet usage by employing panel data techniques and using data on 23 countries from 2008 to 2017. Findings indicate one-way causality from internet usage to tourist arrivals and crime rates. Results also show a high level of persistency in tourist arrivals and moderate persistency in crime and theft. Furthermore, internet usage and population density were found to increase tourist arrivals. The author also found that inflation may increase crime and theft. In conclusion, countries should take urgent steps to decrease inflation to ensure a safer country and they can employ information and communication technologies for security improvement and tourism development.
