Background: about the survey
The Worldwide Cost of Living is a bi-annual (twice yearly) Economist Intelligence Unit survey that compares more than 400 individual prices across 160 products and services. They include food, drink, clothing, household supplies and personal care items, home rents, transport, utility bills, private schools, domestic help and recreational costs. The survey itself is a purpose-built internet tool designed to calculate cost-of-living allowances and build compensation packages for expatriates and business travelers. The survey incorporates easy-to-understand comparative cost of living indices between cities.
