Our Changing World, inspired by the work of Hans Rosling, includes an article from the Economist, definitions from wikipedia, a Hans Rosling TED Talk, and a custom dynamic data visualization made by me, Nathan Hass. The data visualization was made using Processing, an open source programming language created by Ben Fry and Casey Reas. The data for this visualization was acquired from the Guardian Data Store. The additional content on the page is intended to better contextualize the data visualization, enhancing the comprehension of the user.

This project was created under the guidance of Jan Kubasiewicz and Brian Lucid at the Massachusetts College of Art and Design.

Fertility Rate

The fertility rate of a population is the average number of children that would be born to a woman over her lifetime if she were to experience the exact current age-specific fertility rates through her lifetime, and she were to survive from birth through the end of her reproductive life.

Life Expectancy

Life expectancy is the number of years that a person is expected to live as determined by local statistics.

Population

Population is amount of people living in a specified area.

Project Explanation

The dynamic data visualization above was created in Processing with data found on the Guardian Data Store. This project was initially inspired by the work of Hans Rosling. In the his TED talk featured below, Rosling speaks to the unique ability that dynamic data visualizations have to help us better understand our world. By creating
a curated experience in which users can parse through large amounts of data in real time, the user is given the ability to learn through discovery and observation.

User Findings

While playing with this tool, users have stumbled upon a variety of interesting and telling facts. I have included a few samples of this below. If you find yourself making more discoveries or simply want to share your thoughts on the project, please contact me at info@ourchangingworld.net.

  •  Traditionally, the divide between First World and Third World has been shown the relationship of between Fertility Rate and Life Expectancy. In 1950, there was a clear divide between First World and Third World continents. The first world continents, North America, Europe, Oceania all had high life expectancies and low fertility rates. The Third World continents, Asia, Africa, and South America all had low life expectancies and high fertility rates.
  •  By 1978, China’s Population was as large as the world Population in 1950.
  •  In 1950, Europe’s population was 22% of the world population. Because it has not grown as fast as the other continents, now it only consists of 8% of the world population.
  •  It is projected that in 2037, Africa’s Rapidly growing population will equal that of North America, South America, Europe, and Oceania combined.

Making Data Dance

The Economist | An Excerpt from Dec 9th 2010

“The biggest myth is that if we save all the poor kids, we will destroy the planet,” says Hans Rosling, a doctor and professor of international health at the Karolinska Institute in Sweden. “But you can't stop population growth by letting poor children die.” He has the computerised graphs to prove it: colourful visuals with circles that swarm, swell and shrink like living creatures.

For the past four years Dr Rosling's mesmerising graphics have been impressing audiences on the international lecture circuit, from the TED conferences to the World Economic Forum at Davos. Instead of bar charts and histograms, Dr Rosling uses Lego bricks, IKEA boxes and data-visualisation software developed by his Gapminder Foundation to transform reams of economic and public-health data into gripping stories. His aim is ambitious. “I produce a road map for the modern world,” he says. “Where people want to drive is up to them. But I have the idea that if they have a proper road map and know what the global realities are, they'll make better decisions.”

The realities that Dr Rosling is trying to highlight have been gleaned from decades of studying statistics. They sound simple enough: that it no longer makes sense to consider the world as divided between developing and industrialised countries; and that people everywhere respond similarly to increasing levels of wealth and health, with higher material aspirations and smaller families. “There is no such thing as a ‘we' and a ‘they', with a gap in between,” Dr Rosling says. “The majority of people are living in the middle—although the distance from the very poorest to very richest is wider than ever.” The best measure of political stability of a country, he believes, is whether fertility rates are falling, because that indicates that women are being educated and basic health services are being provided. “The only way to reach sustainable population levels is to improve public health,” he says. “Child survival is the new green.”

Communicating these realities to students in his international-development classes at Uppsala University proved problematic, however. “I used to make huge photocopied sheets of Unicef statistics for the students on income, life expectancy and fertility rates around the planet. But it didn't change their world view, it didn't create another mindset. They still insisted that we were different, that all the Chinese cannot all have a car,” says Dr Rosling. He needed a new way to present his conclusions—a way to turn dusty figures into convincing illustrations.

Innovation in infographics has always been driven by the need to explain difficult things, Dr Rosling points out. “Florence Nightingale is known as a nurse, but she also made a new kind of pie chart showing how many soldiers in the Crimean war died from military action and how many from disease.” Nightingale's famous “coxcomb” chart from 1858 demonstrated that improving hygiene in British military hospitals slashed mortality rates. She said its design was intended “to affect thro' the eyes what we fail to convey to the public through their word-proof ears.”
