4. Another implication of population momentum is its effect on the labor force; more specifically the distribution of the labor force. We established earlier that population momentum occurs when a population continues to grow despite the replacement fertility level being met. Meaning that there are more children being born. When there are more children being birthed for that time being until the child is able to work they become dependents meaning that they don't do much to "contribute" to their society. Which leads to an unfavorable dependency ratio. When the children reach the age to work that countries dependency ratio will change and become favorable.
