I'll let others interpret this information. A ranking of the cost of living in various cities around the world ranks San Salvador 242 out of 276 world cities for the cost of living. The survey indexes the cost of living for a typical expatriate from the US, with the index set so the cost of living in New York City = 100. In the index, the most expensive city was Tokyo with an index of 126.03 and the least expensive was Harare, Zimbabwe with an index of 17.12. San Salvador had a figure of 63.34, or 37% less than New York.
