Journal SORT

SORT is an international journal published by the Statistical Institute of Catalonia, appearing twice-yearly in English, and aiming for the highest standards in methodological and applied research on Statistics and Operations Research.

Impact Factor: 1.6 / 1.4 (5 yrs)

SORT was indexed in the "Science Citation Index Expanded" beginning by volume 31 (1) 2007. In June 2023 the Impact Factor 2022 of SORT tracked by Clarivate Analytics has been released: 1.6.

The Impact Factor is established by dividing the number of times articles published in 2020 and 2021 were cited in 2022, based on a search of the Science Citation Index Database, by the number of articles published in the previous two years (2020 and 2021).

The 5-year journal Impact Factor is the average number of times articles from the journal published in the past five years have been cited in the JCR year. It is calculated by dividing the number of citations in the JCR year by the total number of articles published in the five previous years.

This information will be updated on summer 2024.

In 2023, SORT has also renewed the certificate of excellence given in 2011 by Fundación Española para la Ciencia y la Tecnología which guarantees publishing and scientific quality for the next year. SORT represents the third series of the Quaderns d'Estadística i Investigació Operativa (Qüestiió), published by Idescat between 1992 and 2002, which in turn followed from the first series "Quaderns d'Estadística, Sistemas, Informàtica i Investigació Operativa" (1977–1992). The three series of Qüestiió have their origin in the "Cuadernos de Estadística Aplicada e Investigación Operativa", published by the Universitat Politècnica de Catalunya until 1977.
