title: The causes of induced abortion.
abstract: Abstract   In drawing conclusions about the causes of induced abortion, Treffers (Population Studies 20, pp. 295ff) assumed that spontaneous abortion is unrelated to psychological and sociological variables. It is suggested that these assumptions may be false. Some remarks are appended on the mode of ascertainment of abortions and its relation to their estimated incidence.
