The cost of living for an expatriate is affected by both the availability and prices, of goods and services representative of an expatriate lifestyle, local inflation, and the exchange rate between the home and host country. As a result the cost of living has a significant impact on an expatriate’s salary package, explains cost of living experts, Xpatulator.com. 
According to Xpatulator.com's latest research Tokyo is, overall, the most expensive place in the world to live. The cost of groceries, healthcare, and household accommodation in Tokyo is the highest globally, Caracas is, overall, the second most expensive place to live, and is the most expensive place in the Americas. Hong Kong is, overall, the third most expensive place to live, mainly due to the high cost of household accommodation. Geneva is fourth most expensive followed by Japan's second most expensive city, Osaka. (See January 2011 Cost of Living Top 20 Ranking right).
The forecast for 2011 is that we are likely to see food shortages, largely as a result of poor harvests in Russia, Canada and Ukraine, a heat wave in Argentina and floods in Australia, Sri Lanka, Brazil and South Africa, all of which will inevitably lead to higher prices later this year. According to the UN’s Food and Agriculture Organisation (FAO), food prices in December 2010 had already surpassed their previous high in 2008. Given the impact of food on most country's CPI (inflation) baskets, we can also expect higher inflation in 2011.
This is not all bad news. High food prices are good for farmers and are an added incentive for farmers to produce what we need. Although 2011 will see price increases, 2012 should see prices come down because this year's higher prices will incentivise farmers to plant more this year.
The Organization of Petroleum Exporting Countries (OPEC) has said recently that demand for oil in 2011 will be stronger than it previously forecast owing to the recovery in the global economy. Demand has already pushed oil prices to nearly $100 a barrel in early January 2011. Given the impact of a high oil price on energy, manufacturing and transport costs, we are likely to see production costs increasing this year.
Consensus amongst economists appears to indicate that the US Dollar will struggle to make gains in 2011. Research shows that it may rise against the euro, for the first six months of 2011. However when it comes to other world currencies, the U.S. Dollar will continue to weaken.
Cost of living data we collected between October and December 2010 has been used to calculate global cost of living indexes relative to New York (i.e. the index for New York is 100). The cost of living indexes represent the cost of living as at 1 January 2011. The indexes have been compiled and reported on a quarterly basis since 2007 for use in calculating international expatriate salary purchasing power and cost of living allowances.
The prices and quantities of goods and services covering 13 basket groups, representing different categories of costs experienced by expatriates were collected for 300 international locations. The results are reported as indexes based on an algorithm of the raw data together with available indexed data from global agencies, such as the World Bank and the United Nations, and local agencies within each country.
What will the cost of living rankings look like at the end of 2011? We expect higher cost of living indexes in places exposed to higher inflation as a result of higher food and oil prices. Those places that use the US Dollar, or who have currencies that are fixed against the weakening US Dollar, will find imports becomming more expensive. Overall we expect Europe, South America and Asia-Pacific in particular to become relatively more expensive places to live, while the United States should become relatively less expensive, in global terms, particularly with respect to domestically produced goods and services.
