The Nature Index is a database that tracks institutions and countries/territories and their scientific output since its introduction in November 2014.
Each year, Nature Index ranks the leading institutions (which can be companies, universities, government agencies, research institutes, or NGOs) and countries by the number of scientific articles and papers published in leading journals.
The Nature Index attempts to objectively measure the scientific output of institutions and countries, taking into account differences in quality.
Therefore, only articles published in 145 selected high-quality journals are counted.
