“The report is based on an index composed of more than 40 quantitative and qualitative indicators.”
Those 40 indicators are grouped into four categories: personal safety, health security, infrastructure safety, and digital security. Here’s a listing of those five American metropolises, along with their summary global rank and rankings in each category:
- “Personal Safety: This category measures the more traditional aspects of a city’s safety in terms of its levels of crime and illegal activity, relying on factors such as the level of police engagement (input) and the prevalence of violent crime (output).”
- “Health Security: This category measures a city’s health security based on factors such as the ratio of hospital beds to population size (input) and life expectancy (output).”
- “Infrastructure Safety: This category measures the safety of a city’s infrastructure, based on factors such as the quality of its roads (input) and the number of deaths from natural disasters (output).”
- “Digital Security: This category measures a city’s digital security based on factors such as dedicated cyber security teams (input) and the frequency of identity theft (output).”
In overall rankings worldwide, Japan has two cities in the Top 10 (Tokyo ) and Osaka ), with Singapore ranking second. Three central European metro areas (Stockholm , Amsterdam , and Zurich ), two Australian cities (Sydney  and Melbourne ), and Canada’s Toronto (8) outranked tenth-seed New York City.
