Bangladesh capital Dhaka has been ranked the second least liveable city in the world while Damascus ranked the worst, according to the Economist Intelligence Unit annual global survey.

Civil war and terrorism resulted in cities like Damascus ranking poorly and unavailability of adequate infrastructure is responsible for the low score in Dhaka.

Every city was 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.

Dhaka scored an overall of 38 out of a possible score of 100.

Meanwhile, in stability, Dhaka scored 50, healthcare 29.2, culture and environment 40.5, education 41.7 and in infrastructure 26.8.

The liveability ranking considers that any city with a rating of 80 or more will have few, if any, challenges to living standards. Any city with a score of less than 50 will see most aspects of living severely restricted.

Meanwhile, Vienna of Austria ranked on the top of most liveable cities with an overall score of 99.1.
