Staying safe while traveling is a topic which continues to be relevant as terrorist attacks are no longer a surprise and mass shootings seem to be increasingly common. Is almost every destination in the world a potential danger?

In fact, according to the latest Safe Cities Index, some places pose considerably more risk than others. The report was released late last year by The Economist Intelligence Unit, the research and analysis division of The Economist Group, a London-based company that specializes in international business.

The index ranked the safety of 60 international cities across four categories, including personal security, which scored each city on factors such as the number of terrorist attacks, crime rates, threat of military conflict and threat of civil unrest.

The Safe Cities Index was first published in 2015, and the not-so-good news in the second version released in 2017 is that levels of personal security appear to have declined in the past two years, said Christopher Clague, a managing editor at The Economist Intelligence Unit and the creator of the index.
