20 World most beautiful places

The world's most livable cities is an informal name given to any list of cities as they rank on a reputable annual survey of living conditions. Three examples are the Economist Intelligence Unit's "Liveability Ranking and Overview", "Mercer Quality of Living Survey", and Monocle's "Most Livable Cities Index". Liveability rankings are designed for use by employers assigning hardship allowances as part of job relocation. There have been numerous arguments over the expansion of livability rankings for other purposes. However, the annual city rankings attract extensive media coverage, and are a popular topic of discussion.^{[citation needed]}
