Today in human geo we talked about the effect of the population pyramid. This image tells us the population of the country while also telling us whether it is male or female and what the ages are.
There are three categories, pre-childbearing ages, childbearing ages, and non-childbearing ages.
We looked at Canada's population pyramid and saw that most of its population is over the childbearing ages and so it causes the population to decrease. This is the same situation that japan has because they have a high life expectancy. Another contributing factor was the wars that Japan fought in. This resulted in Japans decrease in population.
