The Economist Intelligence Unit’s liveability survey.
How the rating works:
The concept of liveability is simple: it assesses which locations around the world provide the best
or the worst living conditions. Assessing liveability has a broad range of uses, from benchmarking
perceptions of development levels to assigning a hardship allowance as part of expatriate
relocation packages. The Economist Intelligence Unit’s liveability rating quantifies the challenges
that might be presented to an individual’s lifestyle in any given location, and allows for direct
comparison between locations.
Every city is assigned a rating of relative comfort for over 30 qualitative and quantitative factors
across five broad categories: stability; healthcare; culture and environment; education; and
infrastructure. Each factor in a city is rated as acceptable, tolerable, uncomfortable, undesirable
or intolerable. For qualitative indicators, a rating is awarded based on the judgment of in-house
analysts and in-city contributors. For quantitative indicators, a rating is calculated based on the
relative performance of a number of external data points.
The scores are then compiled and weighted to provide a score of 1–100, where 1 is considered
intolerable and 100 is considered ideal. The liveability rating is provided both as an overall score
and as a score for each category. To provide points of reference, the score is also given for each
category relative to New York and an overall position in the ranking of 140 cities is provided.
