Demographic change refers to the shifts in these factors over time, leading to changes in the overall composition of a population. This can include changes in the age distribution, population growth or decline, and shifts in the geographic distribution of the population. Demographic change has significant implications for social, economic, and political systems, as it can impact workforce dynamics, healthcare needs, and overall societal structure. **
