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.
