Indian metros - despite their sheen inside India - have not found a spot among the top 20 cities to live in globally.

None of the Indian cities did well on any of the five key indicators considered in a study, whose eresluts are reflected in the rankings.

The study took stock of five key livability indicators – good governance, urban infrastructure, environmental friendliness and sustainability, quality of life and economic vibrancy in ranking 64 cities around the world. With 36 cities, Asia had the largest number of cities evaluated in the study.

Singapore emerged as the most liveable Asian city and the third from the top on the global list behind Geneva and Zurich.

The report also added, "Every day, about 200,000 people move into cities and towns and by 2050, seven in 10 will live in cities. This presents challenges for governments to provide access to clean water, affordable housing and good sanitation."
