A. Identify each of the three population pyramid shapes by describing the demographic features it represents. Then, give an example of a country that could currently be plausibly represented by it. B. Explain how a population pyramid can be used to:

demonstrate demographic transition.
identify migration transition patterns.
project a country’s future needs.

The population pyramids are a very useful tool that can be use to map out populations in elderly, children, and those who are middle aged. This can help countries determine most of their population, and where they're located, which can also help a country determine where to spend money for schools, banks, nursing homes, doctors offices, and more.

The expansive population pyramid is described as the pyramid representing the young and growing, for example, the U.S. would use this as a way to map out schools, school funds, and necessary items a child would need.

The constructive population pyramid is described as a representation of the elderly and shirking, this could be used by say Ireland to map out the medical care, Pharmacies, and any other necessary items and locations an elderly person would need.

The stationary population pyramid is known as the no growth map which represents little or no growth in the population, a country such as The U.S. could use this map during the "Baby Boomer" era to map out when it stopped, or when the population was increasing at a slower rate.

With these three types of population pyramids, countries can easily determine where to spend funds for much needed services, and where most need to be located for the majority of the population.
