Herfindahl-Hirschman Product Concentration Index Export

This indicator is a measure of the dispersion of trade value across an exporter’s products. A county with a preponderance of trade value concentrated in a very few products will have an index value close to 1. Thus, it is an indicator of the exporter’s vulnerability to trade shocks. Measured over time, a fall in the index may be an indication of diversification in the exporter’s trade profile. The user has the option of selecting product clusters, which will return the index with calculated only for that specified subset of products. Note that if a country exports only a single product, then the indicator returns no value. Note: This dataset uses mirrored data instead of country reported data.
