This total is then divided by the number of citable items, such as articles and reviews, published in those same two source years. The resulting figure is not arbitrary; it is a direct product of the indexing protocols and the specific universe of journals under consideration, making it a reproducible, albeit imperfect, measure.

This specific metric, calculated annually by Clarivate Analytics for journals indexed in the Science Citation Index Expanded or Social Sciences Citation Index, assigns a number indicating the average number of citations received per peer-reviewed document published in that journal over a preceding two-year window.
Grant committees may consult these metrics to identify leading voices and robust research environments, associating higher values with greater visibility and potential impact within the global research community. Researchers, institutions, and funding bodies frequently rely on this figure as a shorthand gauge of prestige and reach, despite ongoing debates about its validity as a sole measure of scientific quality.
