Nature Index

The Nature Index is a database of author affiliation information collated from research articles published in an independently selected group of 82 high-quality science journals. The database is compiled by Nature Research. The Nature Index provides a close to real-time proxy of high-quality research output and collaboration at the institutional, national and regional level.

The Nature Index methodology

The Nature Index includes primary research articles published in a group (n=68; see list of journals) of high-quality science journals. The journals included in the Nature Index are selected by a panel of active scientists, independently of Nature Research. The selection process reflects researchers’ perceptions of journal quality, rather than using quantitative measures such as Impact Factor.

Article output is counted in three ways:

  1. Article count (AC): where a count of one is assigned to an institution or country if one or more authors of the research article are from that institution or country, regardless of how many co-authors there are from outside that institution or country.
  2. Fractional count (FC): that takes into account the percentage of authors from that institution (or country) and the number of affiliated institutions per article. For calculation of the FC, all authors are considered to have contributed equally to the article. The maximum combined FC for any article is 1.0.
  3. Weighted fractional count (WFC): a modified version of FC in which fractional counts for articles from specialist astronomy and astrophysics journals have been down weighted. These journals encompass a much larger proportion of the total publication output of these fields than any other field covered by the Nature Index. The WFC allows ordering of institutions and countries so as not to give undue emphasis to these fields. The weighting is achieved by multiplying the fractional count from these astronomy and astrophysics journals by a factor of 0.2. This down weighting is in proportion to an approximation of the level to which astronomy and astrophysics articles are overrepresented compared to the total publication output of other fields covered by the Nature Index.
