What is an age structure?
An age structure is represented by an age pyramid. The three major groups are pre-reproductive, reproductive, and post-reproductive. A triangular-shaped pyramid represents a stable population. A bell-shaped polygon is characterized by equal numbers of young and middle-aged organisms. An urn-shaped age structure indicates a declining population. This structure is characterized by a high percentage of young organisms.
