The shapes of age pyramids can be classified as follows:
- Triangular-shaped age pyramids indicate a high number of pre-reproductive individuals, a moderate number of reproductive individuals, and even fewer post-reproductive individuals. This type of population is anticipated to grow or expand.
- Bell-shaped age pyramids occur when pre-reproductive and reproductive individuals are nearly equal in numbers or percentages, with relatively fewer post-reproductive individuals. This population is expected to remain stable.
- Urn-shaped age pyramids exhibit low numbers or percentages of pre-reproductive individuals, a maximum number of individuals in the reproductive age group, and a small number of individuals in the post-reproductive age group. Such a population is considered to decline.
