  I analyze the postdoctoral career tracks of a nearly-complete sample of
astronomers from 28 United States graduate astronomy and astrophysics programs
spanning 13 graduating years (N=1063). A majority of both men and women (65%
and 66%, respectively) find long-term employment in astronomy or
closely-related academic disciplines. No significant difference is observed in
the rates at which men and women are hired into these jobs following their
PhDs, or in the rates at which they leave the field. Applying a two-outcome
survival analysis model to the entire data set, the relative academic hiring
probability ratio for women vs. men at a common year post-PhD is H_(F/M) = 1.08
(+0.20, -0.17; 95% CI); the relative leaving probability ratio is L_(F/M) =
1.03 (+0.31, -0.24). These are both consistent with equal outcomes for both
genders (H_(F/M) = L_(F/M) = 1) and rule out more than minor gender differences
in hiring or in the decision to abandon an academic career. They suggest that
despite discrimination and adversity, women scientists are successful at
managing the transition between PhD, postdoctoral, and faculty/staff positions.
