This is a "must-watch" video as it is closely related to what we discussed this week. I'm developing it into another extra-credit activity and will elaborate that in Lab next Thursday 3-10-2011.
Please post your comments here. Here are some suggestions:
- Discuss the relationship between Life Expectancy and Income per person.
- Discuss the use of graphics as tools to visualize Data. Specifically, look at the graph,
What is the vertical axis?
What is the horizontal axis?
Then explain the bubbles:
What does each bubble represent?
What does the size of the bubbles represent?
What does colour represent?
- How do you think the Life Expectancy variable was measured for each country?
- What is another term used to describe the Income per person in a country?
- How was the situation in 1800?
- Ect.

The vertical axis represents average life expectancy which is a measure of a country's health. The horizontal axis represents income per person and has been adjusted to account for inflation and purchasing power according to the speaker. Each bubble represents a country and the color of the bubbles indicates what part of the world each country is located in. The size of the bubble represent the population of the country.
ReplyDeleteThe graph shows the changes in health and income over time and how they are related. In 1800 much of the world was in the same general area in terms of life expectancy (under 40 years) and there was not a huge difference between the income levels of the poorest and riches countries. Over time this has shifted dramatically. As countries became wealthier their health improved and the life expectancy increased so that those countries that became wealthier also had longer life expectancies. Over time the entire graph did shift above 40 years of life expectancy but some became much higher than others and the shift in income was also very marked. You can see from the progression that wealth and health are definitely related variables. Probably the most significant gap you can see in the graph is how much more spread out the wealth of the world became over the year. Some countries have become much more wealthy and others are in the same place they were in 1800 so the gap between the wealthiest and longest living and the poorest and shortest living is much farther apart than it once was.
I saw a TED talk by this gentleman where in addition to showing the fancy graph seen here he also illustrated similar points (he was talking about poverty and population growth) using IKEA boxes. It was neat to see the juxtaposition of high tech graphical representations next to more low-tech three dimensional ones. Thank you for sharing this.
It is interesting video indeed. The speaker was talking on the situation from 1809 until 2009.
ReplyDeleteThe vertical axis(x)represents average life expectancy at birth in year while the horizontal axis (y) represents income per person in dollar and has been adjusted to account for inflation and purchasing power. Each bubbles represent a country, size represent population, while each color represent a continent.

Vertical Axis: Life Expectancy
ReplyDeleteHorizontal Axis: Average Income per person
Bubble Represents: Countries
Size of bubble: Population
Color: Section of the world
I believe that life expectancy would have to be found from public hospitals, or government kept data. Nowadays it's kept in databases. Another term for income per person may be individual earnings, but I'm not sure what is meant by that question. In 1800 all the countries were segregated in their own economies and average lifespan was under the age of 40. I feel as soon as trade began the countries with resources, technology, or services took off. The industrial revolution may have had a part in the explosion of economic growth as it was during that time period.
I'm glad Mrs. Coffey said something about TED. I've seen this as about a 15 minute short explaining different situations in the world. I could watch that site all day. (And sometimes do)
I agree with the others who have posted here. This is a good example of where graphs and graphics can be used to simply demonstrate a topic that could be very difficult to get your arms around. I'm not going to go through and talk about the axis and what not, as that has been addressed very well by other posters, but what I found to be the most interesting is the amount of similarities there were in life expectancy and income in countries around the world 200 years ago. The amount of spread that is demonstrated in this graph of today is remarkable. What is also remarkable is the number of countries that have experienced little to no change over the last 200 years. There is a lot going on in this graph demonstrating that change, and it is an exceptional way of portraying it to an audience that might otherwise not understand. I think he did an excellent job of making a point and demonstrating a means to support it.
ReplyDeleteVery interesting video. The x axis represents average life expectancy and the y axis represents per capita income. The bubbles are nations and their size represents their population. The color represents the continent on which each nation is located.
ReplyDeleteThe situation in 1800 was pretty bad, life expectancy below 40 years for everyone. I like that the narrator pointed out that there are still large disparities in wealth within these nations but from a macroeconomic standpoint, it is a phenomenal illustration. I have always wanted to see an analysis like this used to study the impacts of farm policies on the aggregate number and size in acres of American farms over a number of years. The same could also be done for technological innovations like steel plows or modern irrigation.
In any case, this is a pretty clear picture of the link between industrialization and quality of life.
Seems kind of redundent now, but the vertical axis is life expectancy, and the horizontal axis is the average income per person. The bubble represents countries and the color is the section of the planet.
ReplyDeleteI, also, agree with the others that have posted on here. This video is a good graphical representation of the progression (or lack thereof considering life expectancy early on) of the industrialization in relation to its effect on humans.
I will also second the notion that TED videos are fantastically useful and interesting.

A little late commenting, but this is a really good visual because as the timeline moves, it's interesting to watch how the different countries move up and around the income increases as it bobbles around in life expectancy. It helps make sense of the information as opposed to seeing a plain, flat graph. It was interesting seeing what the life expectancy was in 1800 and seeing what it is now.
