    This study extends the multiregional stable population model to include both sexes, moving beyond single-sex and single-region assumptions. The findings offer a more comprehensive demographic analysis for migrating populations.

    Area of Science:

    • Demography
    • Population Studies
    • Mathematical Biology

    Background:

    • The stable population theory traditionally assumes closed, single-region populations, ignoring migration's impact.
    • Existing multiregional models by Rogers focus on single-sex populations with internal migration.

    Purpose of the Study:

    • To extend the multiregional stable population model to a two-sex population.
    • To incorporate a birth function dependent on both sexes for a more realistic demographic analysis.

    Main Methods:

    • Development of a two-sex multiregional stable population model.
    • Mathematical formulation incorporating interregional migration and sex-specific birth rates.

    Main Results:

    • The established model provides a framework for analyzing population dynamics in multi-region, two-sex systems.

  • Demonstrates the feasibility of extending stable population theory to more complex demographic scenarios.

    • Conclusions:

    • The two-sex multiregional stable population model offers a significant advancement in demographic analysis.
    • This model is crucial for understanding population stability and structure in populations with migration and both sexes.
