I appreciate the hard work that went into this, but we still have to be careful as this is a very tricky measure. E.G. Colombo, Sri Lanka : http://www.numbeo.

I appreciate the hard work that went into this, but we still have to be careful as this is a very tricky measure. E.G. Colombo, Sri Lanka : http://www.numbeo.com/cost-of-living/city_result.jsp?country=Sri+Lanka&city=Colombo http://www.numbeo.com/cost-of-living/city_result.jsp?country... "Colombo" is actually pretty big and diverse. Depending on which area and even street you turn into, which collection of shops you go to, the price will vary wildly. You can see this especially with regard to Bread (66.14 - 165.00), Tomato (60.00 - 150.00) etc... I'm sure this will be very helpful in areas where this is not the case, but I don't think it's applicable where finer granularity is really needed. Good way to gauge this is to see how wide the green bar is and how different the prices. If you see a swath of wide green bars, then you know you need finer granularity or the chart isn't applicable due to the volatility in price.
