    The ratio-correlation regression method accurately estimates substate population demographics. For Virginia, a basic, nonstratified regression equation yielded the best results for age and race composition estimation.

    Area of Science:

    • Demography
    • Statistical Modeling

    Background:

    • Accurate substate population estimates are crucial for policy and resource allocation.
    • The ratio-correlation (regression) method is widely recognized for its accuracy in population estimation.

    Purpose of the Study:

    • To evaluate the effectiveness of the ratio-correlation method for estimating substate population age and race composition.
    • To compare the performance of basic multiple regression with its variants.

    Main Methods:

    • Employed the ratio-correlation (regression) method for population estimation.
    • Tested variants including stratification and averaging estimates from simple regression equations.
    • Applied methods to Virginia localities for age and race composition analysis.

    Main Results:

    • The nonstratified multiple regression equation provided the most satisfactory results for Virginia localities.
    • Compared to stratified approaches and averaged estimates, the basic model was superior in this context.

    Conclusions:

    • The nonstratified multiple regression equation is a highly effective tool for estimating substate population age and race composition, particularly in the studied Virginia region.
    • Further research may explore the generalizability of these findings across different geographic areas.
