Nature Index is a database of 145 high-quality journals selected by leading active researchers. It currently covers publications in the biological sciences, chemistry, earth and environmental sciences, health sciences, and physical sciences. Tables can be displayed for academic, government, corporate, healthcare, and NPO/NGO organisations. The social science and the humanities are not included.

Countries and institutions are ranked according to Count, the number of times an author is listed as co-author of a publication, and Share, the percentage contribution to publications.

The top ten countries, in order, are China, the USA, Germany, the UK, Japan, France, Canada, South Korea, India, and Switzerland.

This year’s overall academic institutions table is led by Harvard, but the rest of the top ten are Mainland Chinese universities. China reigns supreme for physical sciences, earth and environmental sciences, and the USA performs well for biological and health sciences.
