population pyramids

Today in human geography class with mr.schick we took many notes in our notebooks about the various topics we discussed. The topic we discussed most was about the population pyramids. The population pyramid is the "chart" that sorts the boy to girl ratio in comparison to a certain age range. Their are three types of population pyramids. Those being either a Christmas tree, a box, or a cup. The country Bangladesh is considered to have a Christmas tree shaped pyramid. The United States and Sweden are considered to be box pyramids. Japan is considered to be a cup pyramid. Mr schick then brought up a Russian band who was very vulgurous and dirty minded, so knowing me I researched this topic and the song was very very amusing.
