SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

Electoral Studies is an international journal covering all aspects of voting, the central act in the democratic process. Political scientists, economists, sociologists, game theorists, geographers, contemporary historians and lawyers have common, and overlapping, interests in what causes voters to act as they do, and the consequences. Electoral Studies provides a forum for these diverse approaches. It publishes fully refereed papers, both theoretical and empirical, on such topics as relationships between votes and seats, and between election outcomes and politicians' reactions; historical, sociological, or geographical correlates of voting behaviour; rational choice analysis of political acts, and critiques of such analyses; the formal and behavioural properties of electoral systems; and work in game theory, political economy, or social choice relevant to elections. The recent emergence of new democracies in many parts of the world provides a wealth of new information, and scope for testing hypotheses.
On specific topics of particular interest to the community, the Journal accepts collections of 4-6 short articles that form "special symposia." Electoral Studies permits the publishing of short notes and papers extending previous empirical findings. All article formats are subject to "double blind" peer review.
Months of publication: January, April, July and October
