Quality of life around the world
The misery index was created by the economist Arthur Okun in the 1960s. The index is calculated by adding the unemployment rate, the lending rate and the inflation rate minus percent change of GDP per capita.
Another famous tool used for the comparison of development of countries around the world is the Human Development Index, which takes into account such factors as life expectancy at birth, literacy rate, education level and gross national income (GNI) per capita.
Economic conditions affect the life expectancy, which is much higher in the wealthiest regions. With a life expectancy of 85 years, Hong Kong led the ranking the countries with the highest life expectancy as of 2019. On the other hand, Central African Republic was the country with the lowest life expectancy, where a male born was expected to live 51 years as of 2021.
The Global Liveability Index ranks the quality of life in cities around the world, basing on political, social, economic and environmental aspects, such as personal safety and health, education and transport services and other public services. In 2019, Vienna was ranked as the city with the highest quality of life worldwide, while Damascus proved to be the world's least livable city.
