Demographic trends refer to the patterns and changes in the characteristics of a population over time. These characteristics can include age, gender, race, and migration patterns. For example, many countries are experiencing an aging population, where the proportion of older individuals is increasing due to longer life expectancies and lower birth rates. Another important aspect of demographic trends is urbanization, where more people are moving from rural areas to cities. This shift can lead to changes in economic opportunities, housing demands, and social dynamics. Understanding these trends helps governments and organizations plan for future needs and challenges in areas like healthcare and education.
