The formula for the Child dependency ratio is,
[tex]\frac{Population\text{ 0-14}}{Working\text{ age population 15-64}}\times100[/tex]Given:
[tex]\begin{gathered} Population\text{ 0-14=53,244} \\ Working\text{ age population 15-64=206,922} \end{gathered}[/tex]Therefore,
[tex]Child\text{ Dependency Ratio=}\frac{53244}{206922}\times100=25.731435\approx25.731[/tex]Hence, the Child Dependency Ratio is
[tex]25.731[/tex]
