exports concentration

This indicator measures the sectoral concentration of a country’s exports of merchandises. Highly concentrated exports are a source of vulnerability. The export concentration index is derived from a Herfindahl-Hirschmann index applied to exports of merchandises (excluding services) as categorized by the three-digit level of the Standard International Trade Classification (SITC). Performance score from 0 to 100. The lowest score reflects the best situation.
