Final answer:
Demography in anthropology is the study of how human populations change over time and space. It involves examining population size and density, which can affect adaptation, resource competition, and reproductive encounters. Demography is a statistical study that explores birth rates, death rates, and life expectancies.
Step-by-step explanation:
Demography in anthropology refers to the study of how human populations change over time and space. It is a branch of human geography related to population geography. Geographers study how populations grow and migrate, how people are distributed around the world, and how these distributions change over time. When it comes to how many people live per unit of land, demography looks at population size and density. Population size refers to the total number of individuals in a population, while population density refers to the number of individuals per unit area. These factors can affect various aspects such as the potential for adaptation, competition for resources, and reproductive encounters between individuals. Overall, demography is a statistical study that examines various population characteristics, including birth rates, death rates, and life expectancies. It provides insights into how populations change and interact with their environment.
