A guide to the Nature Index


The Nature Index is a database of author associations and institutional relationships. The index tracks contributions to research study posts released in premium natural-science and health-science journals, picked based upon track record by an independent group of scientists.

The Nature Index offers fractional and outright counts of post publication at the institutional and nationwide level and, as such, is a sign of worldwide premium research study output and cooperation. Information in the Nature Index are upgraded frequently, with the most current 12 months offered under a Creative Commons licence atnatureindex.com The database is put together by Nature Portfolio.

Nature Index metrics

The Nature Index utilizes Count and Share to track research study output. An organization or a country/territory is offered a Count of 1 for each post that has at least one author from that country/territory or organization. This holds true despite the variety of authors a short article has, and it suggests that the very same post can add to the Count of numerous countries/territories or organizations.

To obtain a nation’s, area’s, area’s or an organization’s contribution to a short article, and to make sure that they are not counted more than as soon as, the Nature Index utilizes Share, a fractional count that considers the share of authorship on each post. The overall Share offered per post is 1, which is shared amongst all authors under the presumption that each contributed similarly. A short article with 10 authors suggests that each author gets a Share of 0.1. For authors who are associated with more than one organization, the author’s Share is split similarly in between each organization. The overall Share for an organization is determined by summing the Share for specific associated authors. The procedure is comparable for countries/territories, although made complex by the truth that some organizations have abroad laboratories that will be counted towards host country/territory overalls.

Adjusted Share represent the little yearly variation in the overall variety of posts in the Nature Index journals. It is reached by determining the portion distinction in the overall variety of posts in the Index in a given year relative to the variety of posts in a base year and changing Share worths to the base year levels.

The bilateral cooperation rating (CS) in between 2 organizations A+B is the amount of each of their Shares on the documents to which both have actually contributed. A bilateral cooperation can be in between any 2 countries/territories or organizations co-authoring a minimum of one post in the journals tracked by the Nature Index.


natureindex.com users can look for particular organizations or nations and create their own reports, purchased by Count or Share.

Each question will return a profile page that notes the nation or organization’s current outputs, from which it is possible to drill down to find out more. Articles can be shown by journal, and after that by post. Research study outputs are arranged by discipline. The pages note the organization or nation’s/ area’s leading partners, along with its relationship with other companies. Users can track an organization’s efficiency gradually, develop their own indexes and export table information.

This supplement

The Nature Index 2023 Rising stars supplement is based upon the Nature Index database, covering research study posts in 82 natural-science journals released in between 2015 and 2022. Changed Share is determined by changing Share worths to 2022 levels.

The tables rank organizations by their outright modification in adjusted Share from 2017 to 2022. The tables likewise offer the portion modification in adjusted Share 2017– 22.

The tables in this supplement reveal the leading increasing nations and organizations in general, the leading increasing organizations by area, and the leading increasing organizations in each discipline.
