  4. D

Cevap

The dependency ratio of the Local Government Area is 80%80\%.
The correct answer of 80%80\% is determined by summing the non-working age groups (36,00036,000 youth + 12,00012,000 elderly = 48,00048,000 dependents) and expressing this total as a percentage of the economically active working-age group (60,00060,000). Computing 48,00060,000×100\frac{48,000}{60,000} \times 100 yields 80%80\%.

Adım Adım Çözüm

1
Calculate the total dependent population
Dependents=36,000 (under 15)+12,000 (65 and over)=48,000\text{Dependents} = 36,000 \text{ (under 15)} + 12,000 \text{ (65 and over)} = 48,000
The dependent population consists of children under 15 years and elderly adults 65 years and above.
2
Identify the working-age population
Working Age Population=60,000\text{Working Age Population} = 60,000
The economic support base comprises individuals between the ages of 15 and 64 years.
3
Apply the Dependency Ratio formula
Dependency Ratio=(48,00060,000)×100=80% \text{Dependency Ratio} = \left(\frac{48,000}{60,000}\right) \times 100 = 80\%
The dependency ratio expresses the number of dependents per 100 working-age individuals.
