Tokyo and Singapore has topped the list of world's safest city listed down by The Economist.
The Economist's Safe Cities Index looked at 50 cities and ranked them on more than 40 metrics that spanned four main categories i.e. digital security, health security, infrastructure safety and personal safety, the Huffington Post reported.
Osaka, Japan and Stockholm, Sweden were ranked at third and fourth spot respectively.
Riyadh, Saudi Arabia, Johannesburg, South Africa, Ho Chi Minh City (Saigon), Vietnam, Tehran, Iran, and Jakarta, Indonesia were some of the cities that were considered most dangerous cities to live in.
The report notes that wealth and economic development is closely linked to city safety but certainly does not guarantee it.
Researchers also stated that being statistically safe is not the same as feeling safe.
