A week and a half ago, I pointed out the
gender imbalance
apparent in the September issue of
Geology.
My particular gripe was that it would be hard to achieve gender balance
in my ongoing
geopoetry series if issues (like the September one) had three or
fewer papers by women authors. With
encouragements from commenters and the geotwitter rock stars, I had a slightly
deeper look into what is going on with gender in geology, by recording the given
name-assumed gender and author order for a year’s worth of Geology articles.
In total, this included 239 papers with a total of 1164
authors. The number of authors per paper
ranged from 1 to 19. Of these authors, 64% were male, 19% were female, and 16%
were initials. Initial authors excluded from the analysis; Most (57%) of them
were on papers with six or more authors, so I assume that initialization was
generally a space-saving exercise.
Looking only at uninitiated papers, the M/F ratio is 76.9%
to 23.1%. This is not too different to the
professional gender balance quoted
here (76% M) and is slightly better than the
decade-old numbers on assistant professor hires (23% F), but is substantially
worse than the (similar era) graduating PhD student ratio (38% F). So the
implication is that the Geology gender ratio mostly reflects post-grad school anti-female
filtering.
As for author order, the observed vs expected ratios (given
the gender ratio) are shown in the figure below. Due to the small size of the data set and the
large number of individual categories, none of these deviations are
statistically significant; the probability of sole author papers being seven M
to zero F is about 14%- not high, but not enough to convict either. The M/F of first authors, second authors, etc. was generally within a few percentage points of the mean ratio, and always within counting stats.
And a quick Monte
Carlo* suggests that the probability of getting three
or fewer female first authors in any particular issue is about 28% (see below),
based on 10,000 random author list generations for 20-paper issues.
This is only a simulation, of course. It will take the
Geological Society of America just shy of 800 years to put out their 10,000th
issue. Let’s hope that gender equity in
academia has been achieved by then.
* Yes, I know there is an analytical solution, but
simulations are more fun and quicker.
