Demographic analysis is the study of population dynamics, including factors such as age, sex, race, income, education level, and geographic location. Researchers in this field analyze data on population changes, trends, and distributions to understand how these factors impact a society or community. By examining demographic patterns, researchers can make predictions about future population growth, migration patterns, and social trends. Demographic analysis is used in a variety of fields, including public policy, urban planning, marketing, and healthcare to inform decision-making and planning for the future.
