At its most fundamental level, population change comes down to three demographic processes: fertility, mortality, and migration. Demography is the scientific study of human populations—their size, their composition, and how they change through births, deaths, and the movement by people from one place to another.

fertility, mortality, and migration. Demography is the scientific study of human populations—their size, their composition, and how they change through births, deaths, and the movement by people from one place to another.Demographers study five processes:
fertility, mortality, marriage, migration and social mobility. These processes determine populations’ size, composition and distribution.Demographers seek to understand population dynamics by investigating three main demographic processes:
birth, migration, and aging (including death). All three of these processes contribute to changes in populations, including how people inhabit the earth, form nations and societies, and develop culture.
