How these indices are derived?
The indices shown here are based on the data collected from various sources including but not limited to government, non-government and scientific organizations. The data from different sources are processed using advanced analytic techniques. The end result can only be as good as the data used and, of course, also depends on the analytic techniques. Since the quantity and quality of data available is generally higher for the developed than for the developing countries, the calculated indices are expected to be more robust for the developed countries.
The calculation of climate index (which combines temperature, rainfall and snowfall information in one simple index) is robust since it is based on, at least, last 20 years of average climate.
The NewsClouds are based on news gathered from a range of newspapers and news organizations around the world, and updated daily. The NewsClouds reflect the frequency of words that occur in news with bigger words occurring more frequently. The examples available here illustrate how effective the NewsClouds are in capturing primary news events.
Tourist safety index
The tourist safety index is difficult to update on a continuous basis because of the frequency at which underlying socio-economic information is updated. It is recommended that tourist safety index must be assessed in conjunction with the NewsClouds to assess current conditions in a country.
The price index is based on hotel prices and the relative prices of a typical basket of goods that is used for assessing consumer price index. We also account the daily variations in currency exchange rates.
