UPSC CAPF – 2016
According to the 18th Mercer Quality of Life Study released in 2016, Vienna was ranked as the city with the best quality of life in the world for the seventh consecutive year.
Mercer’s Quality of Life survey evaluates living conditions based on factors like political and social environment, economic environment, socio-cultural environment, medical and health considerations, schools and education, public services and transportation, recreation, consumer goods, housing, and natural environment.
Other cities consistently ranked high in the study included Zurich, Auckland, Munich, and Vancouver. Major global cities like London, Paris, and New York typically rank much lower due to factors like congestion, crime, and cost of living.
