Population Pyramids

Today we are on a community bell because of All Saints Day. We have mass after 2nd mod and it causes all of our classes to be shortened. At the start of today's class, we just sat around and talked, played on our computers, or did whatever we wanted. After about 10 minutes Mr. Schick started the lesson. We started our last topic of the unit, learning about population pyramids. We learned that there are 3 types of pyramids, the box, the Christmas tree, and the cup. The box is for developed countries with a growing population. This is for countries like the United States, and Sweden, that have similar amounts for all age groups. The cup is for countries that are developed but have a declining population. This is for countries like Japan, where there are more old people than young. The third and final pyramid is the Christmas tree, which is for developing countries, that have a high fertility rate and a low life expectancy. This is for countries like 3rd world countries, that have more younger people than old.
