Refer to your course materials and class notes for definitions of the dependency ratios. The table below separates the population into geographical regions and age groups.

The Child Dependency Ratio (CDR) is calculated by dividing the population under the age of 18 by the working-age population aged 18 to 64. The Senior Dependency Ratio (SDR) is calculated by dividing the population aged 65 and older by the working-age population aged 18 to 64.

What is the justification for the calculation above?

Where those below the age of 15 are children,

Child Dependency Ratio = Population of those below 15 years/ Working Age (15-64 years

=23,671/75,347

= 0.314

What is the Old Age Dependency Ratio?

Where aged people are those above 65,

Old Age Dependency Ration = Population of those Greater than 65 years/ Working Age Population (15-64 years)

= 14,256/75,347

= 0.189

What is the Age Dependency Ratio?

Age Dependency Ratio = Population of (0-15) + Population of 65 and above/ Working Age Population (15-64)

ADR = (23671 + 14, 256)/ 75 347

= 37, 927/ 75, 347

= 0.503
