For a number of years, Copenhagen has ranked high in international surveys for its quality of life. Its stable economy together with its education services and level of social safety make it attractive for locals and visitors alike. Although it is one of the world's most expensive cities, it is also one of the most liveable with its public transport, facilities for cyclists and its environmental policies. In elevating Copenhagen to "most liveable city" in 2013, ''Monocle'' pointed to its open spaces, increasing activity on the streets, city planning in favour of cyclists and pedestrians, and features to encourage inhabitants to enjoy city life with an emphasis on community, culture and cuisine. Other sources have ranked Copenhagen high for its business environment, accessibility, restaurants and environmental planning. However, Copenhagen ranks only 39th for student friendliness in 2012. Despite a top score for quality of living, its scores were low for employer activity and affordability.
