A survey has come up with some interesting information about the cost of living in our major cities. Tokyo is still the most expensive city in the world. Osaka is second and Moscow third, on a par with Hong Kong. Many European cities have gone down the rankings because their exchange rates have become weaker against the US dollar. Moscow's exchange rate has also become weaker, but Russia has a much higher inflation rate than many European countries. So prices in Moscow are among the highest in Europe. But there is one advantage of living in Moscow. The underground is excellent very cheap and much more comfortable than the one in London. New York is the most expensive US city. This is because the US dollar is stronger than many other currencies.
