👉 Demography, or demographic mathematics, is the branch of statistics that studies population dynamics and trends. It involves using mathematical models to analyze and predict changes in population size, structure, and composition over time. Key concepts include birth rates, death rates, migration patterns, and age distribution, which are often represented through equations and statistical methods. Demographers use these tools to understand how factors like socioeconomic conditions, healthcare access, and policy changes impact population growth or decline. This field is crucial for urban planning, public health, resource allocation, and policy-making, helping to forecast future needs and challenges related to population size and structure.
