  In this work, we analyse all existing data related to the number of incomers
and outcomers (who actually obtain the degree) of the following courses offered
at the Federal University of Santa Catarina: physics teaching, bachelor in
physics, master of sciences in physics and doctorate in physics, corresponding
to the 1998-2017 period, according to their availability. The data point
towards a great male predominance (larger than 76%) and a huge evasion of both
sexes (in average, less than 20% of the undergraduate incomers obtain the
degree), the evasion being lower in the postgraduate courses and always
slightly higher for women.
  The average number of incomers and outcomers per year decreases as the
students advance from graduate to postgraduate courses, although many students
in the postgraduate courses come from other institutions. The proportion of
women decreases as the carrier advances.
  The results indicate the need of complementary studies that can help the
identification of the causes of such a high evasion in order to minimize them.
