    This study used Monte Carlo simulations to analyze family planning. Natural fecundability significantly impacts averted births and potential fertility more than fetal loss selection.

    Area of Science:

    • Demography
    • Reproductive Health
    • Statistical Modeling

    Background:

    • Understanding factors influencing family planning choices and natural fertility is crucial for reproductive health.
    • Heterogeneity in natural fecundability and fetal loss risks complicates accurate demographic modeling.
    • Previous models often overlook the impact of marriage duration and desired family size on contraceptive status.

    Purpose of the Study:

    • To investigate the effects of various factors on family planning status and natural fecundability.
    • To develop methods for estimating births averted and potential fertility among family planning users.
    • To assess the relative importance of selection for fetal loss versus natural fecundability.

    Main Methods:

    • A Monte Carlo simulation incorporating heterogeneity in natural fecundability and fetal loss.

  • Analysis of selection based on marriage duration at contraceptive status recording and desired family size.
  • Development of formulae for estimating births averted and potential fertility, validated by simulation.

    • Main Results:

    • Selection for natural fecundability is a more significant factor than selection for fetal loss in determining averted births.
    • Contraceptive status of sterile women, including those unaware of their sterility, was revealed.
    • Simulation results confirmed the developed formulae for estimating fertility and births averted.

    Conclusions:

    • Natural fecundability plays a primary role in the effectiveness of family planning interventions.
    • Accurate estimation of potential fertility and births averted requires accounting for individual fecundability variations.
    • The simulation model provides a robust framework for analyzing complex reproductive dynamics.
