title: Some ways of incorporating both sexes in models that become stable.
abstract: The author presents "four models of birth trajectories in which the female age-specific fertility rates have been assumed to depend on the relative age compositions of both sexes.  In each case, the rates fluctuate but approach their limiting values and the age compositions become stable."
