A population has 3 million people aged 0-14, 5 million aged 15-59, and 2 million aged 60 and above. What percentage of the total population is dependent?

Answer and explanation

Correct answer: 50 percent

Dependent population is calculated by adding the young and elderly groups, because they are generally outside the main working-age group used in this question. Children number 3 million and people aged above 60 number 2 million, so the dependent population is \(3+2=5\) million. The total population is \(3+5+2=10\) million.

The dependent percentage is therefore \(\frac{5}{10}\times100=50\%\). Hence, option A is correct. The 15–59 age group is treated as the working-age population and is not included in the dependent total. Options B, C, and D result from using an incorrect numerator or denominator, rather than adding the two specified dependent groups.
