Answer:
Step-by-step explanation:
The age dependency ratio is a measure that compares the size of the dependent population (people who are too young or too old to work) to the size of the working-age population. It is calculated by adding the percentage of the population under 15 (child population) to the percentage of the population over 65 (old age population) and dividing by the percentage of the population aged 15 to 64 (working-age population).
In this case, we are given that the child population is 42% and the old age population is 8%. This means that the working-age population is 100% - 42% - 8% = 50%.
To calculate the age dependency ratio, we add the percentage of the child population (42%) to the percentage of the old age population (8%) and divide by the percentage of the working-age population (50%):
Age dependency ratio = (42% + 8%) / 50% = 50%
Therefore, the age dependency ratio of this country is 50%, which means that for every 100 people of working age, there are 50 dependents who are either too young or too old to work.
