The dependency ratio is a measure of the number of dependents aged zero to 14 and over the age of 65, compared with the total population aged 15 to 64. This demographic indicator gives insight into the number of people of non-working age, compared with the number of those of working age.It is also used to understand the relative economic burden of the workforce and has ramifications for taxation.
Definition
The dependency ratio is the ratio of the population aged 0 to 14 and those aged 65 and over to the total population aged 15 to 64. This demographic indicator reveals the relationship between the non-working-age population and the working-age population. It is also used to understand the relative economic burden on the workforce and impacts taxation.
Origin
The concept of the dependency ratio originated in demographic studies, initially used to analyze the impact of population structure on the economy. With the development of socio-economic conditions, especially during industrialization and urbanization, this indicator has been widely applied in policy-making and economic analysis.
Categories and Features
The dependency ratio is typically divided into two categories: the youth dependency ratio and the elderly dependency ratio. The youth dependency ratio refers to the ratio of the population aged 0 to 14 to those aged 15 to 64, while the elderly dependency ratio is the ratio of those aged 65 and over to the population aged 15 to 64. A high dependency ratio may indicate a higher social and economic burden, as more resources are needed to support the non-working population.
Case Studies
In Japan, due to severe aging issues, the elderly dependency ratio has been rising, leading to labor shortages and slowed economic growth. The government has responded by raising the retirement age and encouraging female employment to alleviate this issue. Another example is some African countries, where the youth dependency ratio is high, requiring government investment in education and job opportunities to ensure future economic development.
Common Issues
Investors might misunderstand the implications of high or low dependency ratios on the economy. A high dependency ratio is not always negative; it may reflect a country's high birth rate or longevity. The key is how the government manages and utilizes these demographic changes.
