Demographic shifts refer to changes in the characteristics of a population over time. These changes can include variations in age, race, gender, and migration patterns. For example, an aging population may lead to a higher percentage of elderly individuals, while increased immigration can diversify the cultural makeup of a community. These shifts can impact various aspects of society, including the economy, education, and healthcare. As the population ages, there may be a greater demand for healthcare services and retirement planning. Similarly, changes in birth rates can influence school enrollment and workforce availability.
