Global population trends result from varying levels of population growth and decline among countries. This video provides a simple and compelling overview of population trends that created a world of 7 billion people in 2011 and predict growth to 8 billion by 2023.
In addressing the question, "Why is world population rising even though the actual growth rate has declined," the video outlines the population pattern that sees countries transition from a situation characterized by high birth rates and high death rates to one in which births and deaths have stabilized.
In outlining the reasons for population trends, the video invites students to explore a number of issues related to population dynamics - aging populations; family planning; status of women in the developed and developing world; education and birth rates; carrying capacity; ecological footprint. The Population Resource Bureau (PBR) site includes a number of complementary resources that help students pursue these issues after watching the introductory video.
