Population Pyramid

I forgot to do a blog yesterday however I'm doing it now. We talked in class about the population pyramid. The population pyramid is a type of graph which allows you to see the amount of people in the population make up a certain age group. This very helpful when figuring out if a country's population is rising or falling. You can tell it's rising if the chart expands at the bottom and is smaller at the top. This also tells you the country is pre-industrial because they're having so many children and not a very long life expectancy.
