today in class we watched a video that was about population pyramids. I liked watching the video I think it was easier to take notes on. I learned about demographic transition. which has to do with population. we learned that in pre-industrial areas the life expectancy is going up and the child mortality is lowering. also in industrial areas the child mortality lowers and most people move from rural areas to urban areas to be closer to the factories that they work at. lastly we learned about post-industrial areas and that both there birth and death rate lower because the are more stable and there births ad deaths almost even out.  We also learned about things that can effect the population pyramid. one thing is war it effects the pyramid by there being more women then men in a age period because men usual go to war and not women and it effects the amount of elderly over time because a lot of people could have died during the war, the birth rate usual goes up after because its usually a happy time and the men are back home so the start having babies. also if a country has a one child policy there is a low amount of births and the old people begin to dominate the country also there might be sex selective abortions so there might be a decrease in the amount of babies in a certain sex.

today in class we started to talk about new things. we started to learn about political geography. in other words how the world is organized. the world is organized in countries which are an identifiable land area. they are also organized by nations which are a population with a common culture. the last way is by a state which means a population under a single government and can be synonymous with "country". a better definition of nation is, a group of people with a shared identity think of it as a culture group nations are groups of people, larger than a single tribe or community, which may share a common language, institutions, religion, and/or historical experience. and independent state might have characteristics such as has space of territory which has internationally recognized boundaries, has people w there on an on going basis, has economic activity and organized economy which regulates foreign and domestic trade and issues money, has the power of social engineering,

today in class we watched a video about global health. we learned that the world used to have a very low income and life expectancy. the life expectancy is the x-axis and it goes from 25-75 years. the y-axis is the income and it starts at 400-40,0000.400 means they at sick and poor. 40,000 means they are rich and healthy. the life expectancy in 1810 was under 40 yrs. in every country besides U.K. and Netherlands. when a countries industrialization increases so does the life expectancy and income.in 1948 the graph was as wide spread as it has ever been and there is countries that there life expectancy is over 75 and has an income average of 40,000 and there is some areas that have a life expectancy just over 25 and the only make 400 dollars of income. I liked watching the video because it helped me understand the graph a lot more and understand what we where talking about a lot more.

today in class we took a test on the world leaders. the test was easier than I thought it was going to be. i thought I was going to have to know the type of government they have and i couldn't remember what those where. The part about the special facts about the leaders was the hardest part and i think i did good on that. but there was some i really didn't know and I'm pretty sure i got them wrong. but i think all together i did pretty good on the test. also i was very stressed because i had an F in the class and you still hadn't got my project so i thought i was going to fail. but i was just sending it to the wrong email. so i think i will be able to get my grade up to and A with those two assignments turned in. I liked this class a lot and I'm going to miss it next semester.
