A study of optimum population levels--a progress report.

S F Singer

    Proceedings of the National Academy of Sciences of the United States of America
    |December 1, 1972
    PubMed
    Summary

    This study develops a methodology to calculate optimum population levels by creating a Quality of Life Index (Q-index). This approach integrates economics, technology, and environmental factors to inform population policies and technology assessment.

    Area of Science:

    • Interdisciplinary study integrating economics, technology, natural resources management, environmental science, and demography.

    Background:

    • Existing economic measures like Gross National Product (GNP) do not fully capture societal well-being.
    • Population growth and economic development create externalities that impact quality of life.

    Purpose of the Study:

    • To develop a methodology for calculating "optimum levels of population."
    • To create an Index for Quality of Life (IQL or Q-index) to guide population and technology policies.

    Main Methods:

    • Reshuffling national income accounts to derive the Q-index from GNP.
    • Projecting the Q-index based on population levels, distribution, and technological assumptions.
    • Analyzing resource consumption (minerals, energy) and environmental impacts.

    Main Results:

    • The study provides a framework for quantifying the relationship between population dynamics and quality of life.
    • It highlights how economic growth can lead to increased costs associated with negative externalities.
    • The methodology allows for the assessment of new technologies' impact on economic well-being.

    Conclusions:

    • The developed methodology offers a rational basis for governmental population policies in developed and developing countries.
    • It serves as a tool for technology assessment, evaluating the economic impact of innovations.
    • Mathematical models can diagnose consequences of public and private policy decisions.
