Vienna is the best city to live in, Baghdad is the worst.

According to Mercer Consulting Group, Vienna has an excellent infrastructure, safe streets, and a good public health service.

These advantages allow the city to take its rightful place in the world, which is not the case with Baghdad, where it was given the last place. The German and Swiss cities of Zurich, Munich, Düsseldorf, Frankfurt, Geneva and Bern also made the top-ten list of the best cities in the world.
The Austrian capital, with its quaint buildings, public parks and extensive bicycle network, has recently reduced the cost of an annual public transportation pass to 1 euro per day. Few serious crimes have made the city, with a population of 1.7 million, the world's best in terms of quality of life.
In the "personal safety" ranking, due to clashes between demonstrators and police, Athens (among European cities), ranks last.
Oslo slipped from 15th place to 24th because of the mass murder in July by Breivik.
Baghdad ranked last, both in terms of security (numerous attacks on foreigners and locals) and quality of life. Political and economic turmoil in Africa and the Middle East lowered the rankings for Libya, Egypt, Tunisia, and Yemen. The cities of Auckland, Wellington, Sydney, Melbourne and Perth were in the top -20 for "quality of life", while Singapore was in 25th place.
200 cities of the world took part in the rating. Russian cities were not included in the first top-50.

1 Vienna, Austria 6 Vancouver, Canada

2 Zurich (Switzerland) 7 Frankfurt, Germany

3 Auckland, New Zealand, 8 Geneva, Switzerland

4 Munich, Germany 9 Bern, Switzerland

5 Düsseldorf, Germany 10 Copenhagen, Denmark
