today in class we watched a video about population and how it grew over the past two hundred years ago, or just about. It showed that around 1810 all countries and nations were in stage one with a high birth rate and high death rate. Around the industrial revolution European countries and the Americas started to grow in population and death rates started to rapidly decline and entered stage two and three, but the Asian region, the Middle East, and sub- Saharan Africa stayed in stage one. It showed how after time the Asian countries started to catch up, but sub-Saharan Africa was still behind, but not in stage one. It showed how during wars, plagues and tragedies, the countries would rapidly drop in life expectancy and how after wars, curtain countries would rapidly grow, and curtain countries would rapidly drop or not change at all depending on the results of the war. It eventually got into the 2000s and showed how sub- Saharan countries were far behind because they do not have the recourses that countries like the United States have. However, no country is in stage one.

11/16 Notes

- Sex Ratio

• Defined as the number of males per hundred females in the population
• developed countries have more females than males because they tend to live about seven years longer than men.

-The Demographic Transition

• Why natural increase rises and falls

1. stage 1: Low Growth

marked by very high birth and death rates

no long term natural increase

no country is presently in stage one

2. stage 2: High Growth

rapidly declining death rates and very high birth rates 

high natural increase

Europe and North America entered stage 2 as a result of the industrial revolution (~1750)

3. stage 3: Moderate Growth

marked by rapid decline in birth rates and steady death rates

natural increase is moderate

gap between CBR and CDR is narrower in stage three countries than stage two countries

population grows because CBR is still greater than CDR

4. stage 4: Low Growth

marked by very low birth and death rates 

no long term natural increase and possibly a decrease

country reaches stage four when population gains by CBR are diminished by losses because of CDR

condition known as zero population growth (ZPG)

demographers more precisely defined ZPG as the TFR that produces no population change population change results from immigration

- Declining Birth Rates

• two successful strategies for lowering birth rates 

1. improve education and health care 

emphasizes improving local economic conditions so that increase wealth is allowed to education and health programs seeking lower birth rate

    2.   Contraception

more immediate results reaped than pervious approach

met with greater resistance because it goes against culture and religious beliefs 

Why is Global Population Increasing?

• components of population growth
• natural increase
• about 82 million people are added to the population of the world annually
• more than 95 percent of the natural increase is clustered in poor countries
• fertility- total fertility rate (TFR)
• TFR for the world is 2.42
• exceeds 5 in sub-Saharan Africa, while 2 or less in nearly all European countries
• mortality- Infant mortality rate (IMR)
• measure used by geographers to better understand death rates in society
• defined as the annual number of deaths of infants under one year of age, compared with total live births
• usually expressed per 1,000 births rather than percent
• IMR is 5 in developed countries and 80 in sub-Saharan Africa

Today in class we talked about the test. I zoned out most for most of it. It is okay I got an 89 so its no big deal. I am not really worried because that is not a bad grade. I guess I am going to do better on the next test. I forgot I had Biology homework so I am going to have to do that in my free period tomorrow, but that is okay. I only got four wrong on the test and it was the ones that I did actually know, but it is okay.

Today in class we talked about what movies that Mr. Schick worked for. It was interesting. I will not be in class Wednesday or Thursday because of the play and we do not have class Friday, so I am wondering when I can take the test. Hopefully it will be sooner rather than later. I am also hoping that I do no have to make up to much work, but I have a feeling that I will have to. It will be okay though because I will take the time to do the homework and do it when I can. I am now just trying to get all my work done during my free periods, that way I have less to do at home and so I can go do other things, but this week is going to be a long hard week.

Ted Talk

Today we watched TED talks about population pyramids. It was about how each country's population will increase or decrease over time and what the reasons for that are. I almost fell asleep in because of the Basilica trip. The bus was a horrible time because people are unnecessarily obnoxious   . Someone was bribed to drink as much water as possible the person managed to drink about 7 to 10 small waters. That was at least a little entertaining. After the first TED talk we watched another TED talk about a model who is basically considered what our society "prefers." She explained how opposite gender and race does not get the benefits she would get by looking "beautiful." I found that interesting.

Today in class we talked about population pyramids for different cities. Most of them were special because they had a major difference between age group. The military base had mare man than women at the age people would normally enroll in the military until the age they would retire from the military which would usually be thirty to forty. The city in Michigan had more college students because The University of Michigan was a big impact of their population. Springfield, Illinois was a more boxy pyramid because it contains a lot for every age group. The city in Florida had a Jurassic measurement in elder people because it is where a lot of elders move and then live. We then looked at what the world's population pyramid looked like and in the future it becomes more and more boxy and eventually it starts to become more like the cup shape.
