Financial capitals of India and Pakistan - Mumbai and Karachi - were the cheapest cities in the world to live followed by New Delhi, according to a new survey.
Nepalese capital of Kathmandu and Algerian capital of Algiers were the other locations among the world's five cheapest cities, the Economist Intelligence Unit's (EIU) worldwide cost of living index found.
The EIU found that Mumbai shared the top ranking with Karachi in the survey based on costs of over 160 items ranging from transport, utilities, food and clothing.
"Income inequality means that household spending levels are low on a per capita basis, which has kept prices down, especially by Western standards," the EIU said in reference to India in its 2013 survey, which ranked Tokyo as the most expensive city in the world.
Other cities in this year's top five included another Japanese city, Osaka, followed by Sydney, Oslo and Melbourne.
Australian cities rank high mainly due to inflation and currency swings among the 131 cities surveyed, Jon Copestake, editor of the index, said.
