Population Pyramids: How to Read them, How to Find them

In this video recorded for the University of Maine at Augusta Social Science program, we talk about population pyramids. What are population pyramids? How can one read a population pyramid? Where can examples of population pyramids be found? These questions are addressed briefly here. Population pyramids are a central visual representation of social structure in demography, the study of the number, distribution, and composition of people. Demography offers perhaps the conceptually simplest vision of social structure, since it is fundamentally based in mere counts. Empirically speaking, counting people turns out to be very difficult indeed.
