What is the term for the study of population?

The term for the study of population is demography. Demography focuses specifically on the statistical study of human populations, including the analysis of their size, distribution, density, and the changes within them due to births, deaths, migration, and aging. This field provides insights into trends and issues related to population characteristics, which are vital for various sectors such as policy-making, urban planning, and social services.

Population dynamics, while related, refers more broadly to the changes in population size and composition over time and is often studied within the context of demography. Sociology encompasses a wider range of topics related to human social behavior and societal structures but is not limited to the study of populations. Ecology studies the relationships between organisms and their environment, which may involve population studies but is not focused solely on human demographics. Thus, demography is the most precise term for the study of population.
