Population Pyramids

Continuing our discussion and note taking from yesterday, we learned about population pyramids. Population Pyramids show the population number or percent of men and women in an area(country). To make the graph more accurate men and women are split up into two different sides and each are split up in to several age groups five years apart. Youngest people at the bottom of the pyramid and oldest at the top. There tends to be three primary different shapes one being a Christmas tree, another a box, and a cup. The Christmas tree indicates that the bottom of the pyramid is significantly wider than the top and tends to slim out. Christmas tree population pyramids show up for developing Countries. These countries’ growth rates are slow, there is a high birth rate, and there is a short life expectancy. Some developing countries include Namibia and Bangladesh. Box shape pyramids mean that each age group has around the same amount of people. Box population pyramids tend to be for developed nations where there is usually low infant mortality, a slow population growth, and a long life expectancy. Sweden and the United States are two great examples for this. In class we started the third type of population pyramid, the cup, but we didn’t finish. However, I do know that this population pyramid represents a country with a low birth rate and has a shrinking population which causes the larger portion of it’s population to be with the older people living in the country rather than the younger people.
