Demography is the study of the size, composition, and geographic distribution of human populations, and how the population changes due to fertility, mortality, and migration.
MORE PEOPLE ARE ALIVE IN
THIS EXACT MOMENT THAN AT
ANY PREVIOUS TIME IN HISTORY.
In the next 60 seconds, 267 babies will
be born, and 110 people will die.
By the time you’ve finished reading this
introduction, the world’s population will
have increased by around 600 people.
By 2050, our planet will be home to
nearly 10 billion humans, compared
with fewer than eight billion people
in 2020. But population is about more
than facts and figures. The world’s
population is composed of individuals
of all ages whose actions and stories
collectively shape our future.
These pages contain an overview of important demographic processes including fertility, mortality, and migration, and their effects on population growth, decline, and composition. We describe changes in the geographic distribution of the world’s population, historical patterns of global
population growth, and projections for the future.
“Population: An Introduction to Demography” helps us develop a greater understanding of why population trends matter—not just to researchers
and academics but to all of us.
