About this data
The diversification index signals whether the structure of exports by product of a given country or group of countries differ from the structure of product of the world. Diversification index is computed by measuring absolute deviation of the country share from world structure. Diversification index that ranges from 0 to 1 reveals the extent of the differences between the structure of trade of the country or country group and the world average. The index value closer to 1 indicates a bigger difference from the world average. It is constructed as the inverse of a Herfindahl index, using disaggregated exports at 4 digits (following the STIC3).
