The original version of this table (published 20 June 2019) used incorrect fractional counts, percentage changes and article counts to derive the rankings, which meant that some institutions were ranked incorrectly. The data and rankings were corrected on 12 August 2019.

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.

The Nature Index database undergoes regular updating, corrections, adjustment of institutional hierarchies, and removal of retracted papers and thus the live website can differ from the frozen annual tables.

*The change in adjusted FC accounts for the small annual variation in the total number of articles in Nature Index journals. FC values have been adjusted to 2018 levels to calculate the percentage change. For more information on the adjustment, please see the Adjusted metric explainer.
