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.

Political Geography is the flagship journal of political geography and advances knowledge in all aspects of the geographical and spatial dimensions of politics and the political. The journal brings together leading contributions in the field and promotes interdisciplinary debates in international relations, political science, and other related fields. While we welcome articles with an empirical focus or that center on policy implications, all research published in the journal is expected to engage with and advance the subdiscipline's conceptual, methodological, and theoretical literature. We encourage contributions drawn from diverse theoretical and methodological perspectives, covering all scales of inquiry, and from scholars in all parts of the world. Examples include, but are not limited to, research into:
• critical engagement of the theory and practice of geopolitics;
• geographies of sovereignty and the state;
• peace and conflict studies;
• geographies of policy, institutions, and elections;
• feminist, queer, and postcolonial engagements with the political;
• politics of spatiality, networks, and scale;
• intersections of political economy and political geography;
• territoriality, mobility, and identity within and across borders;
• political ecology, the politics of the environment, and post-human politics.
We encourage the submission of full-length, innovative high-quality papers (11,000 words max), in addition to shorter, responsive, and topical editorials and interventions, as well as book review essays and forums.
