Population and Migration and Statistical Analysis

1. The video we watched during class featured Hans Rosling, a man who teaches a Global Health college course (I had to watch the video again because I thought he said Go blef).
2. Hans Rosling constructed a chart which has two separate lines of axis. The y- (or vertical) axis measured lifespan or life expectancy.
3. The x- (or horizontal) axis measured income; wealth.
4. To the lower, left corner of the graph, he dubbed with poor and sick, and
5. The higher, right corner of the graph he described as rich and healthy.
6. In the Demographic Transition chart, birth rate, death rate, and total population were given over time, in five stages. In stage two, a country would be experiencing a high birth rate and a rapidly falling death rate.
7. In the early 1800s, the United States was in stage one.
8. Some countries that are currently in stage five are:
1. Japan (the obvious choice).
2. Russia
3. Italy
4. The United States (if it weren't for its migration rate).
9. In stage one, a country would be experiencing a stable or slow rate of natural increase due to a high birth rate and a high death rate.
10. The Industrial Revolution began in the late 1700s in the British Isles.

In Hans Rosling's graph, certain sections of the world were classified in colors. 

• Europe is brown.
• Asia is red.
• Middle East is green.
• Sub-Saharan Africa is blue.
• The Americas are yellow.

And the size of the circle represented the size of the population.

In 1810, life expectancy for all nations was under 40 years of age, but the United Kingdom and the Netherlands were better off.
