The American consulting company Mercer has published an annual ranking of world cities in terms of quality of life.
The survey considered several factors to determine the quality of living in each city. The rankings take into account factors like recreational facilities, housing, economic environment, consumer goods and availability, public services and transport as well as the political and social environment, natural environment and education options.
Other outstanding cities following Singapore include Tokyo, Hong Kong and Seoul. Luxembourg was named as the safest city in the world, followed by Helsinki in Finland and the Swiss cities of Basel, Bern and Zurich. Western Europe dominates this ranking, however Brussels (47th place) falls considerably between 2005 and 2019 due to terrorist attacks, and Greece (102nd place) also takes a dive due to its slow recovery from the global financial crisis.
The 10 cities at the bottom of the 231-city table were unchanged, with Baghdad ranked last, followed by Bangui in the Central African Republic and Yemen's capital Sanaa. This year, Mercer provides a separate ranking on personal safety.
