In human demography and population studies, “population (human)” refers to the total set of individuals of Homo sapiens occupying a defined spatial, temporal, or social frame, serving as the primary unit of analysis for topics such as fertility, mortality, migration, and population structure. Research addresses population size, age–sex composition, density, spatial distribution, and dynamic processes governed by demographic rates and transitions. Human populations are modeled using formal demographic methods (e.g., life tables, stable and multistate population models) and are central to analyses of population growth, demographic transitions, population health, urbanization, and the interaction between human numbers and economic, environmental, and social systems.
