Population analysis is a field of study that focuses on examining the characteristics and trends of human populations. This includes studying demographics, such as age, gender, race, income, and education level, as well as analyzing patterns of migration, fertility rates, mortality rates, and population growth. Population analysis is often used in social sciences, public health, urban planning, and policy making to better understand and address issues related to population dynamics. Researchers in this field use various statistical methods and data collection techniques to gather information and draw conclusions about different population groups.
