AGE DISTRIBUTION

When drawn as a "population pyramid," age distribution can hint at patterns of growth. A top heavy pyramid, like the one for Grant County, North Dakota, suggests negative population growth that might be due to any number of factors, including high death rates, low birth rates, and increased emigration from the area. A bottom heavy pyramid, like the one drawn for Orange County, Florida, suggests high birthrates, falling or stable death rates, and the potential for rapid population growth. But most areas fall somewhere between these two extremes and have a population pyramid that resembles a square, indicating slow and sustained growth with the birth rate exceeding the death rate, though not by a great margin.
