A new ranking measures city characteristics like sprawl, green space, and pollution to determine livability.

The Economist Intelligence Unit — the city rankings specialists — has a new list claiming the best cities to live. And they have an interesting new livability metrics to judge the world’s cities.

The rankings combined EIU’s popular “Liveability Index” with a new measure that focuses on spatial characteristics. The “Spatially Adjusted Livability Index” takes into account seven characteristics:

 

-Sprawl: using the ”estimated relation between the metropolitan region’s surface and its total population, the overall coherence of the metropolitan form and an estimate of the extent of low density urban fabric.”

-Green space: based on ”the distribution of green spaces within the metropolitan region, the number of local green spaces and the number of metropolitan scale green spaces.”

-Natural assets: using “Google Earth satellite imagery and information from Open Street Map to assign points to cities based on the natural features” and the number of protected areas around a city center.

-Cultural assets: counting the number of UNESCO World Heritage Sites in the vicinity of the cities.

-Connectivity: calculating how many cities can be reached by plane from a city and the average number of flights from that city.

-Isolation: based on the number of large cities near a city.

-Pollution: using World Health Organisation (WHO)’s Air Pollution in Cities database to calculate air quality with a concentration of particulate matter of over 10 micrometres...
