Updated: 16 Sep 2019, 05:37 PM IST Staff Writer The national capital has dropped by six places to rank 118th on a list of the world's most liveable cities due to increase in cases of petty crimes and poor air quality, an annual survey by the Economist Intelligence Unit showed on Wednesday 1/6New Delhi registered the biggest decline in Asia, Mumbai also fell two places since last year to rank 119th on the list topped by Vienna (Austria) for the second consecutive year. The EIU said its ranking of 140 cities is based on their scores in 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.

Several cities, such as New Delhi in India and Cairo in Egypt received substantial downgrades on their scores owing to problems linked to climate change, such as poor air quality, undesirable average temperatures and inadequate water provision,' the report said.
