2020 Research Leaders: Leading government institutions

Table criteria

Footnote

Each year, the Nature Index publishes tables based on counts of high-quality research outputs in the previous calendar year. Users please note:

1. The data behind the tables are based on a relatively small proportion of total research papers, they cover the natural sciences only and outputs are non-normalized (that is, they don’t reflect the size of the country or institution, or its overall research output).
2. The Nature Index is one indicator of institutional research performance. The metrics of Count and Share used to order Nature Index listings are based on an institution’s or country/territory’s publication output in 82 high-quality natural science publications. The publications were chosen by an independent group of researchers. The list is reviewed periodically and journals may be removed or added.
3. Nature Index recognizes that many other factors must be taken into account when considering research quality and institutional performance; Nature Index metrics alone should not be used to assess institutions or individuals.
4. Nature Index data and methods are transparent and the data in the above table is published under a creative commons licence at nature.com/nature-index/.
5. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

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 research leaders tables.

Research Leaders tables from previous years are also updated annually to reflect any changes to the database. This means rankings and metrics may differ from the table when first released.
