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.
