Population Pyramid

Population Pyramid

Today we watched the population pyramid and discussed what it was about. Some facts about the population pyramid are, they are divided by male and female, the youngest age starts at the bottom (0 to 4) and the oldest age is at the top (100+). We also talked about having a population of mostly younger means in the future your population will grow, for example Rwanda's populations is made up mostly younger aged people so as time goes on their population will grow. We also talked about how almost all African countries have a high percentage of people who are young, so their population will grow as well. Two important definitions we discussed are;

1. Industrial Society- makes their economy on machines, makes things like cars, washers, dryers. They make lots of money and buys lots of stuff.

2. Pre-Industrial Society- makes living off plants and crops, does not make lots of money.

Continuing on with class we talked about when population goes up, life expectancy goes up and child mortality goes down. We also looked at Japan's population of pyramid and talked about how most of their population is older therefore when time goes on population will decrease because there will be few percentage of people producing children. Then we answered four questions on the population pyramid.

*4 factors that can alter a trend represented by a population pyramid are:
- Industrialization
-Natural Disasters
-Education of Women
-War

*As a country slows in population growth, its pyramid will become more rectangular
*A population pyramid gives you information about birth rates, actual number of people, and death rates.
* If your in an advanced a state of industrialization the characteristics would be low birth rate, low death rate, stable population, good living conditions and long life expectancy.
