Even More Year-End Stats for 2018

I have one last chart to share from the set for the JGR Space Physics editorial board meeting earlier this month. This is a chart of the authors of JGR Space Physics articles in 2015 and 2016, counting each individual person separately. Two things are shown on this chart: the bars show the number of articles with authors from that country publishing in these two years (scale on the left), while the line shows the citations to papers authored by people from that country in 2017 (the Journal Impact Factor calculation window), with values on the right axis (ICW = in-window citations).


Yes, JGR Space Physics is dominated by authors from the United States. China has about one-third the number of authors and it goes slowly down from there.

What I like about this is the relative flatness of the citations-per-paper line. It’s 3.00 for the US and hovers between 2.5 and 3.0 for all countries in the top 12 (down through Finland). A cynic might suggest that we should publish more papers with authors from Norway and Belgium, as they are near 3.3 average citation value.

Hey, I’m of Norwegian descent. We even made a big batch of lefse this past weekend. I should look into the average citations of my papers and see how they stand up to my counterparts in my ancestral homeland. But I digress…

Note that this chart is for a single year of citations to papers published in the two previous years. The ordering of the countries along the x axis shifts quite a bit from year to year, as does the average citations-per-paper, especially for those towards the right of the scale. This is a snapshot of early citations to recent publications.

In general, I am happy with the flatness of this line. Without doing more analysis into it, I think it means one of two things: (a) we publish with international author lists so these numbers are not independent or (b) we cite papers independent of the author’s country of origin. I hope both are true.

Happy New Year!
