We should all move to Vienna. That's what the Economist Intelligence Unit recommends: In a new report, it ranked Austria's capital as the world's most liveable city. With a score of 99.1 out of 100, Vienna beat out Melbourne for the top spot, which the Australian city had held onto for the past seven consecutive years. This is the City of Music's first time being number one.

The survey ranks 140 cities worldwide based on five categories: stability (including crime and terrorism); healthcare; culture and environment (including level of censorship, temperature, and cultural offerings); education; and infrastructure (including public transportation, housing, energy, and water). Overall, there were improvements in safety and stability this year for the countries surveyed.

Vienna scored a perfect 100 in four out of five categories. The only area in which the city could use a tiny bit of improvement is in culture and environment—though its 96.3 score is still pretty impressive.

The cities that scored best on the list tend to be mid-sized with low population densities and located in wealthy countries. The world's biggest urban centers, such as New York, London, and Paris, may be popular places to live for their unbeatable food and culture, but high levels of crime, congestion, and public transportation issues make quality of life less desirable and drag them down in the rankings.

The top 10 most liveable cities are:

1. Vienna, Austria
2. Melbourne, Australia
3. Osaka, Japan
4. Calgary, Canada
5. Sydney, Australia
6. Vancouver, Canada
7. Toronto, Canada
