Essential Science Indicators SM from Thomson Reuters is a compilation of statistical information (publication, citation and cites-per-paper counts) for scientists, institutions, countries and journals. It is based on 10 years of Thomson Reuters data.

Essential Science Indicators, accessible by subscribers through a web interface, is updated every two months. During the course of a year, the data series presented covers 10 years plus a successive number of recent two-month periods, eventually reaching an 11-year time-span.

At the end of the year, the compilation reverts to a 10-year data set, dropping off the oldest year of the series.
