Nature Index 2018 (Article Count) – Global Overview
The Nature Index is a database of author affiliations and institutional relationships. The index tracks contributions to research articles published in a group of high-quality natural science journals, chosen by an independent group of researchers.
Each year, the Nature Index publishes tables based on counts of high-quality research outputs in the previous calendar year. It is important for users to understand that the data behind the tables are based on a relatively small proportion of total research papers, that they cover the natural sciences only and that outputs are non-normalized (that is, they don’t reflect the size of the country or institution, or its overall research output). We encourage users to combine the free-to-access Nature Index data with information from other sources.
