(October 2009) "Distilled Demographics," PRB's video series, highlights key demographic concepts such as fertility, mortality, and migration. Through these short videos, you can learn demography's real-world application and impact.

In this first video, "Deciphering Population Pyramids," PRB senior demographer Carl Haub shows how population pyramids give us a snapshot of a country's demographic profile. But what do they tell us about a country's past and future? "These videos not only show that demography can be exciting, but also highlight how population trends and issues affects the well-being of us all," says Haub. "Fertility, mortality, and migration—along with other demographic issues—play a major role in determining what kind of opportunities and challenges people face in their communities and countries."
