More population pyramids

     Today in class we watched a video working with population pyramids. This video was a TED talk which I have watched in the past and have really liked listening to them. This video was about how demographers can read and use population pyramids to predict following trends. The video also highlighted the differences between countries population pyramids compared to what there economy is like. It used the trend that post industrial countries or developing countries have a very high birth rate and there population is growing quickly. This is because these countries need a lot of people in their work force. In industrial countries families do not need to have as many kids to succeed so the birth rate is usually about constant with the death rate. In post-industrial countries the society has a lot more automation and less need for work.

The rise of Christianity

 Toady in class instead of reviewing the test we read and took notes on the next three sections. The first section was on the Rise of Christianity and talked about how Jesus' teachings spread. The most important reason they spread was because his teachings brought salvation to all. Christianity was a vision that a Roman emperor had before he went into battle. They won the battle and he made it so Christians would no longer be persecuted.

Test review

  Most of today in class was spent reviewing last weeks test from last week. Class was last mod today so everyone was more lethargic than usual. Since I was the only person to get a 100% on the test I really didn't need the review. The only plus side of reviewing was I had time to write the answers on the test so I could use it without my scan tron sheet. The rest of class time was spent taking notes on the population power point. We discussed immigration and emigration and why. We used the example of Canada and why people would want to immigrate there because their rate is so high. We came to the conclusion that the healthcare paid for by the government was a pull factor in people's decisions to move to Canada.

CIA website facts

     Over the past two days in class we used the CIA website to do research on countries where they are located and some interesting facts about them. On the website we went into the world fact book which has information on every country. The first day we used this website I forgot to do my blog, but what we did was research the top 25 most populated countries and where they are located on a map. This was very easy for me because I already knew where all the countries. The one fact that shocked me was that Bangladesh was the 8th most populated country. This was so interesting because Bangladesh  is a very small country and yet it has over a billion and a half people. This gives it a population density of 1,200 people per square kilometer compared to the united states 35. i used this fact in the second day where we used this sight because I Thought it was very interesting.
