The researchers of the American Harvard and MIT universities concluded a study on economic complexity last year. The atlas analyzes the foreign trade of 128 countries and sets up an economic growth ranking which is based on the so-called Economic Complexity Index (ECI). The basis for the analysis is the quantity and complexity of exported goods and the frequency of exports. Consequently, services and non-export goods were not included in the study.
