caption_attribution_description: English: how difficult it is for a nation to produce the products it sells to other countries
context_page_description: This list orders countries by their economic complexity index, as it was defined and calculated by Cesar A. Hidalgo and Ricardo Hausmann. The ECI was calculated with trade data from the UN Comtrade, the United Nations International Trade Statistics Database, and so the information is only based on exports, not goods produced. The 2009 rankings includes Products Exports Treemaps, also built by the Observatory of Economic Complexity.
