The data I get from is from EIU. It shows the world’s most livable cities,measuring different categories including stability, healthcare, culture and environment, education, and infrastructure.
The ranking attempts to assess which cities across the globe provide the best living conditions, by assigning a score on 30 quantitative and qualitative measures across the five categories with the following weightings:
Healthcare (20%)
Culture & Environment (25%)
Stability (25%)
Education (10%)
Infrastructure (20%)
Of the 30 factors within these categories, the qualitative ones are assigned as acceptable, tolerable, uncomfortable, undesirable, or intolerable by a team of expert analysts. Quantitative measures are given a score based on a number of external data points. Everything is then weighted to provide a score between 1-100, with 100 being the ideal.

Only 173 cities were ranked, so I'm guessing all of these weren't even considered. To be fair, the criteria of what counts as a 'liveable' city are somewhat arbitrary and at the very least not all-encompassing.

I bet those dudes haven't been to Kabul, Bangui, Sanaa or Aden. I would think that being in a war zone trumps everything.
