Population Pyramids

In human geography, we talked about Total Fertility Rate. For example, Nigeria's TFR is almost 7 which would mean the population would be skyrocketing. However, due to other factors such as the prevalence of AIDS in the country the population doesn't increase as much. We also discussed population pyramids which are a type of bar graph that is basically two bar graphs vertically placed next to each other to show the difference between the two. We viewed a few, one I remember was one of the female and male ages population in Japan. I noticed two things, the female stats were generally larger and the second was that people in the 60 year old range were the largest age group. This is interesting, considering most times, you'd think the it would be more the 30-40 year old range.

It can be a hasty here’s-how to-get-to-the-party sketch, an elaborate work of art, or a precise computer-generated product. A map serves two purposes: It is a tool for storing reference material and a tool for communicating geographic information .
