Population Bulletin vol 75. no.1 : An Introduction to Demography

By 2050, our planet will be home to nearly 10 billion humans, compared with fewer than eight billion people in 2020.

Understanding population trends is essential in tackling many of the world’s greatest challenges, among them hunger and malnutrition, poverty, climate change, and disease, including the coronavirus pandemic. Population data are a vital tool for policymakers, business leaders, scientists, and others seeking to make informed decisions on important issues.

This Population Bulletin, “Population: An Introduction to Demography,” provides a basic understanding of demography and demographic processes, including fertility, mortality, and migration, and their effects on the world. First published in 1991 as “Population: A Lively Introduction,” this newly revised edition gives readers a greater understanding of why today’s population trends matter—not just to researchers and academics but to all of us.
