About this data
This indicator reflects the Herfindahl-Hirschmann index measure of the degree of export concentration within a country. The sectoral Hirschmann index is defined as the square root of the sum of the squared shares of exports of each industry in total exports for the region under study. Takes a value between 0 and 1, with 1 indicating that only a single product is exported. Higher values indicate that exports are concentrated in fewer sectors. On the contrary, values closer to 0 reflect a more equal distribution of market shares among exporters. Note that this type of concentration indicator tends to be quite vulnerable to cyclical fluctuations in relative-prices, in a way that commodity price rises make commodity exporters look more concentrated.
