Dependency ratio

Definition

The dependency ratio is a demographic measure that compares the number of dependents, typically those aged 0-14 and over 65, to the working-age population (those aged 15-64). This ratio is significant as it helps to understand the economic burden placed on the productive population, influencing resource allocation, social services, and overall economic growth. A high dependency ratio indicates a larger number of dependents relative to the working-age population, which can strain resources and hinder development.

5 Must Know Facts For Your Next Test

1. The dependency ratio is calculated by dividing the number of dependents by the working-age population and multiplying by 100 to express it as a percentage.
2. Countries with high dependency ratios may face challenges in providing adequate healthcare, education, and social services for their dependents.
3. As countries progress through demographic transition, they often experience a decline in dependency ratios initially due to decreasing fertility rates.
4. An aging population increases the old-age dependency ratio, which can create economic pressures on pension systems and healthcare services.
5. Policy responses to high dependency ratios may include promoting higher workforce participation rates among women and older adults.

Review Questions

• How does the dependency ratio reflect the economic challenges faced by a country during different stages of demographic transition?
  • The dependency ratio provides insight into the economic pressures a country faces as it progresses through demographic transition. In the early stages, a high birth rate results in many young dependents, straining education and health services. As countries move toward lower birth and death rates, they may initially experience a decrease in this ratio, easing pressure on resources. However, as populations age, the old-age dependency ratio increases, leading to new economic challenges related to healthcare and pensions.
• Evaluate how shifts in fertility rates impact the overall dependency ratio within a population.
  • Shifts in fertility rates have a direct impact on the overall dependency ratio. A decrease in fertility rates typically leads to fewer young dependents over time, lowering the youth dependency ratio. This can alleviate some pressure on resources needed for education and child care. However, if fertility rates drop significantly below replacement level, this can lead to an aging population with a higher old-age dependency ratio, which poses its own set of challenges for economic sustainability and resource allocation.
• Assess the potential long-term implications of an increasing dependency ratio on social and economic policies in developed nations.
  • An increasing dependency ratio in developed nations could have significant long-term implications for social and economic policies. As the proportion of dependents grows relative to the working-age population, governments may need to adjust their policies regarding taxation, pensions, and healthcare funding. This shift could lead to increased taxes on the working population or reforms in retirement age and benefits to ensure sustainability. Additionally, these nations may need to consider immigration policies to bolster the workforce and mitigate the economic impacts of a shrinking labor pool.

Related terms

demographic transition: The demographic transition is a model that describes the transformation of a country's population structure from high birth and death rates to low birth and death rates as it develops economically.

fertility rate: The fertility rate refers to the average number of children born to a woman over her lifetime, significantly impacting the dependency ratio by influencing the number of youth dependents.

aging population: An aging population occurs when the median age of a country rises due to declining birth rates and increased longevity, affecting the dependency ratio as there are more elderly dependents.
