Data for 2018
Export Concentration Index, 2018
2018, as UNCTAD’s 2026 release gives it · stored as published, never rewritten
The export concentration index measures how far a country's merchandise exports are concentrated in a few products rather than spread across many. It runs from 0, exports spread evenly across every product group, to 1, a single product — the classic measure of how exposed a country's export earnings are to the price of one or two goods.
Export Concentration Index, 2018 covers 213 countries on 3 measures. São Tomé and Príncipe is highest, at 0.963765; Italy is lowest, at 0.052845. The middle country reads 0.294710. Against 2017, 213 values changed (119 up, 94 down), the same countries are covered.

One year of the 2026 release
Every year in this series comes from UNCTAD’s 2026 release, recalculated on one method, so a change from one year to the next is not a revision. It can differ from what was first published for 2018.
