Of the 2116 journals for which we had adequate data in 2015-2016, 825 showed statistically significant evidence of gender homophily (denoted by α′ > 0), and 1 showed statistically significant evidence of heterophily (α′ < 0), after false discovery rate correction.

In the stacked density plot, the white area shows the number of journals for which homophily was significantly stronger than expected under the null hypothesis (corrected p < 0.05), while the blue area shows all the remainder. Patterns were similar whether α′ was calculated for all authors, for first authors only, or for last authors only. Points in the right panel show α′ for individual journals.
