Rank

Rank information is included for both the JCR Impact Factor and ESI Total Citations. Category ranking is presented by year in descending order for each category in which the journal is ranked in both the JCR and ESI. JCR Impact Factor table also includes the Quartile and JIF Percentile for each year.

ESI Total citations provides rank and quartile, in addition to a graph of Total Citations by JCR years. Click View All Years to expand the number of columns displayed.

Quartiles in JCR on the InCites Platform

Quartiles are defined as the following:

X = the journal rank in category according to the metric (Journal Impact Factor, Total Citations, etc)

Y = the number of journals in the category.

Z = Percentile rank (X/Y)

Q1: 0.0 < Z ≤ 0.25

Q2: 0.25 < Z ≤ 0.5

Q3: 0.5 < Z ≤ 0.75

Q4: 0.75 < Z

Where quartile data differs between JCR on the Web of Science platform and JCR on the InCites platform, the latter should be the source of record for official quartiles.
