Population Pyramids

Population Pyramids

• we use population pyramids to analyze growth ( or decline) of fertility, morality, and migration in cities (males are always on the left of the pyramid and women are on the right)
• three basic shapes

- Christmas tree-- developing nation growth rates are slow; high birth rate, short life expectancy; ex: Namibia
- The box-- slow growth, low infant mortality, slow population growth, and long life expectancy; ex: USA; Sweden
- The cup-- developing nation; negative growth, low birth rate, shrinking population, long life expectancy; ex: Italy; Japan

10/29

Today in class we talked about last Friday's assignment. I did not realize we had to write brief paragraph about each fact about the country we chose. Luckily we were aloud to fix our mistakes. I fixed my assignment and emailed him about it. I hope my grade goes up enough to keep it at an A for this quarter. I think it will happen, but you never know. I did not realize that I had to write five paragraphs about each fact. It will be okay it is not the end of the world. I am just trying to get second honors now, so hopefully my grade does not go down because i have exactly a 4.1 GPA. I do not know how I am passing half my classes because I do not understand half of the material we are doing.

Qatar

        Qatar is a country that is located off of the Persian Gulf. It has a population of 2,314,307 people as of July 2017 and the average age of the people is 25-54.  The population is high compared to how small the country is. It is smaller than Connecticut and bigger than Delaware.

        All of the population is forced to labor and to a lower force, prostitution. Migrants are legally forced to work in poor conditions and get a low pay rate. They are forced to give up passports and are unable to live in poor quality homes. Women are forced into prostitution sometimes.
 
       The population of the men that age is 1,359,383 hundred. The women only have 274,334 people. I found this interesting because most countries have a close to similar rate of men and women and for the population of men and women.This is because of immigration. With that more men immigrated to Qatar than women which explains why there are very few compared to the men.
     
        There are 67.7% are Muslim and 13.8% are Christian or Hindu, and 3.1% are Buddhist, 0.1% of folk religion, 0.1% are Jewish, 0.7% are other and 0.9% unaffiliated. I found that Qatar was close to the more Muslim countries. However, I found it interesting that there are a good bit of Jews in Qatar. It was interesting because you would not expect people with the Jewish religion because it is not really one of those countries.

  Their growth rate is 2.27% the birth rate is 9.6 births per 1,000, and the death rate is 1.5 per 1,000. The N.M.R. is 14.6 per 1,000. This is related to what we are doing in class. The birth rate is super high, which means that the population is growing rapidly. The death rate is way lower than the birth rate.

10/25 Notes

• Net Migration Rate: the difference between the number of person's entering and leaving a country during a year

- an excess of persons entering the country is net immigration

• written as a positive number
• example: Canada has 5.65 migrants per 1,000 population
•                U.S. has 2.45 ( it was 3.62 in 2015)

- an excess of persons leaving the country is net emigrant

• written as a negative number
• example: Mexico has -1.68 migrants per 1,000 population
•  -3.61 two years ago, -3.11 last year  

notes 10/23

Life expectancy

• the average numbers of years to be lived by a group of people born in the same year
• High: Monaco- (89.52 total: 85.63 men, 93.58 women
• #42 : U.S. - (79.68 total: 77.32 men, 81.97 women)
• Low: Chad- (49.81 total: 48.64 men, 51.03 women)
• crude birth rate: number of births per 1,000 of the population
• crude death rate: number of deaths per 1,000 of the population
• rate of natural increase (RNI)
• produced by subtracting the death rate from the birth rate 
• this gives us the annual natural growth rate- in percentage form- for a country or region

but don't forget about migration

Net migration Rate: the difference between the number of person's entering and leaving a country during a year

       - an excess of persons entering the country is the net immigration 

Population and Settlement

More people than ever!

• over 7.5 billion people on the planet right now
• increasing by over 73 million per year
• by approx. 200,00 per day
• 8,377 per hour
• 149 per minute
• 2.5 per second
• 90% of this population growth takes place in the developing countries of Africa, South and East Asia and Latin America

Test

Today we had a test. I think I did well because the test was not that hard. I did seem to have to figure some questions, but for the others I knew what the answer was. I am pretty positive that I passed. We were aloud to work on other homework or anything else we had to do after the test, so I started my math homework. I have no idea what we are doing in that class. It is Friday and I can not wait for this day to end. I just want to sleep and not do homework or worry about school. I am happy that the test is over with, but now we have to learn more material and I am not looking forward to that.
