    Study Notes

    Life Expectancy

    • Life expectancy is the average number of years of life remaining for an individual at a given age (usually at birth).
    • In early Roman times, life expectancy was around 20 years, increasing to 30 years in 1800, 50 years in 1900, and 72 years today.
    • By 2030, life expectancy is expected to rise, with South Korean women reaching close to the 90-year threshold, followed by France, Japan, and Spain.

    Demographic Indices

    • Dependency ratio measures the economic burden on the working population caused by those who are not in the labor force.
    • Other demographic indices include:
      • Median age: the age at which the population divides into equal numbers of younger and older people.
      • Birth and death rates.
      • Sex ratio:
        • At birth: 98.5 males per 100 females.
        • At ages 65+: 83 males per 100 females.
        • At ages 85+: 53 males per 100 females.

    Population Aging

    • Population aging is a significant demographic change that requires adaptations in society.
    • As a population ages, leading causes of death change from acute/infectious to chronic/degenerative diseases.
    • Improvements in food distribution, nutrition, water quality, personal hygiene, public sanitation, education, and economic development contribute to population aging.

    The Significance of Demographic Indices

    • Demographic indices provide a partial picture of demographic change.
    • The number and percentage of the population aged 65+ only tell part of the story.
    • Other indices, such as median age, birth and death rates, and sex ratio, are essential to understand demographic change.

    Global Aging and Economic Performance

    • Declining fertility and fewer children contribute to population aging.
    • Gains in longevity and a longer period of time to work are also significant factors.
    • There are four reasons to be optimistic about global aging and economic performance.

    Demography

    • Demography is the study of why and how populations change over time and become smaller, larger, or older due to fertility, migration patterns, and mortality.
    • Demographers use tools like tables, graphs, and figures to illustrate demographic trends and patterns.
    • Population aging statistics are used to direct social policies and acquire insight into individual and population aging issues.
