How does the shape of age pyramid reflect the growth ... A population pyramid graphically displays the age and gender make-up of a population. As we explained in our post 'What is a Population Pyramid,' the more rectangular the graph is shaped, the slower a population is growing; the more a graph looks like a pyramid, the faster that population is growing. Characteristics of Population (Explained With Diagram) These categories, proposed by Bodenheimer (1985), have considerable value in visualizing the status of a population. In natural population, the age structure is almost constantly changing. In a rapidly growing or expanding population as in the case of bacteria, yeast and housefly, birth rate is high and population growth may be exponential.

Population pyramid - Wikipedia A population pyramid (age structure diagram) or "age-sex pyramid" is a graphical illustration of the distribution of a population (typically that of a country or region of the world) by age groups and sex; it typically takes the shape of a pyramid when the population is growing.
