How can death rate and emigration can decrease of population?

A decrease in the Death Rate typically leads to population growth, as more individuals survive longer, while emigration reduces the population by causing individuals to leave an area. However, if emigration rates exceed the number of births or if significant improvements in healthcare lead to longer life spans without corresponding births, the overall population can still decline. Additionally, if young, working-age individuals emigrate, it can lead to a demographic imbalance, further reducing the population over time. Thus, both factors can interact to influence population dynamics in complex ways.
