In a finding that may baffle many Indians, Mumbai has emerged as the world’s cheapest city to live in, followed closely by New Delhi at the third place. According to the Economist Intelligence Unit (EIU) 2014 “Worldwide Cost of Living” survey, Singapore is on the other end the world’s most expensive city. “But Asian cities also continue to make up many of the world’s cheapest, especially in the Indian subcontinent,” said Jon Copestake, the editor of the EIU report. The reason for the Indian cities scoring high on the lower end is due to inequality between the richest and poorest in India’s major cities, which keeps wages and prices low, while spending is also stifled by government subsidies. The “Worldwide Cost of Living” is a twice-yearly EIU survey that compares more than 400 individual prices across 160 products and services. These include food, drink, clothing, household supplies and personal care items, home rents, transport, utility bills, private schools, domestic help and recreational costs. Other cities making up the top five most expensive cities are Paris, Oslo, Zurich and Sydney, with Tokyo falling to the sixth place.
