The study of population is called [D] Demography. Demography is the scientific discipline that focuses on analyzing and understanding human populations. It involves studying various aspects of populations, including their size, distribution, composition, density, growth rates, and demographic characteristics such as age, sex, race, ethnicity, education, occupation, and marital status. Demographers utilize statistical methods, census data, surveys, and demographic models to investigate population dynamics, migration patterns, fertility rates, mortality rates, and population trends over time.
By studying demography, researchers gain insights into social, economic, political, and environmental factors influencing population changes and their implications for societies and economies. Demography plays a crucial role in informing public policy, urban planning, healthcare provision, resource allocation, and social welfare programs. It provides essential knowledge for addressing challenges such as population aging, urbanization, migration, inequality, and sustainability, contributing to evidence-based decision-making and promoting human well-being.
