Each year the international consulting firm Mercer does a survey to evaluate the quality of living in 221 cities around the world. This year's survey results give Vienna top grades, ranking Austria's capital as the World's Most Livable City for the second time in a row.

The survey compares the political, social and economic climate, medical care, education, and infrastructural conditions such as public transportation, power and water supply.

It also takes into consideration recreational offers such as restaurants, theaters, cinemas, sports facilities, the availability of all kinds of consumer goods from food to cars, as well as environmental conditions - from green space to air pollution.
