  A large-scale, up-to-date analysis of Computer Science literature (11.8M
papers through 2019) reveals that, if trends from the last 50 years continue,
parity between the number of male and female authors will not be reached in
this century. In contrast, parity is projected to be reached within two to
three decades or may have already been reached in other fields of study like
Medicine or Sociology. Our analysis of collaboration trends in Computer Science
reveals shifts in the size of the collaboration gap between authors of
different perceived genders. The gap is persistent but shrinking, corresponding
to a slow increase in the rate of cross-gender collaborations over time.
Together, these trends describe a persistent gender gap in the authorship of
Computer Science literature that may not close without systematic intervention.
