Study Notes
Population Composition
- Population composition refers to the characteristics of a population such as age, sex, race, marital status, education, occupation, income, and household size.
- The sex ratio is the number of males per 100 females.
- A sex ratio of 100 indicates an equal number of males and females.
- A sex ratio greater than 100 indicates more males than females, and a sex ratio less than 100 indicates more females than males.
- The sex ratio in the U.S. in 2014 was 97, meaning there were 97 males per 100 females.
- At birth, there are more males than females, but as people age, more males die earlier, leading to fewer males in older age groups.
- The age distribution of a population demonstrates how many people are in different age groups.
- Younger populations need schools, while older populations may need healthcare and/or pensions.
Population Pyramid
- A population pyramid is a visual representation of the age distribution of a population.
- It shows the number of males (on the left) and females (on the right) in each age group.
- A classic pyramid shape indicates high birth rates and higher death rates.
- A rectangular or barrel-shaped pyramid indicates a more balanced age distribution, often found in high-income countries.
Neo-Malthusianism
- Neo-Malthusians are modern scholars who believe that overpopulation is a global problem due to limited resources and an increasing strain on the environment.
- They argue that rapid population growth leads to environmental degradation, resource scarcity, and social issues.
- Neo-Malthusians advocate for zero population growth to ensure the planet's long-term sustainability.
- They believe that technological innovation is not a solution to overpopulation and instead promotes unsustainable consumption.
Criticisms of Neo-Malthusianism
- The theory has been criticized as being too Eurocentric, focusing on the experiences of Western countries without taking into account the diversity of demographic patterns in non-Western societies.
- Critics argue that the theory doesn't fully account for the role of economic systems and political structures in population growth and resource allocation.
- Some critics believe that demographic transitions are occurring more rapidly in low-income nations due to improved healthcare and access to family planning resources.
- Critics question the linearity of the theory's evolutionary model, suggesting that societies may not follow the same trajectory in their demographic transitions.
