Population Patterns and Demographic Evidence

Why is Niger's population among the youngest in the world while Japan's is among the oldest? Learners calculate birth, death and natural increase rates and doubling times, read population pyramids and dependency ratios, and use the demographic transition model — with its limits — to explain differences between countries. They finish by using demographic evidence to advise a government on schools, jobs and care for older people.
