Despite what you may think, the world is improving

In some ways, at least. Our old friend Hans Rosling (previous Contrarian appearances hereherehere, and here) brings us up to date, and highlights the amazing recent prograss in (parts of) Ethiopia:

Rosling’s Gapminder data visualization software now has some tools you can download to your own computer.

What’s the most important machine in the world?

Our old friend Hans Rosling has a surprise candidate:

Visual data: 200 countries over 200 years

Our old friend Hans Rosling, the Swedish public health statistician whose Gapminder software brings demographic trends vividly to life (previous menions here and here), is back with a new BBC video tracking the health and wealth of nations over two centuries:

If you’d like to drill down into the data and watch a particular country’s progress or compare two or three countries, the Gapminder file on which this video is based will let you do that. You can also download the software to your own desktop. Amazing stuff, and should give pause to those who are certain the world is going to hell in a handbasket.

Is anyone plugging Canadian data into these tools?

Child survival is the new green

In his latest Ted talk, population guru Hans Rosling says improving child survival rates is the counterintuitive path to population control:

Contrarian’s submission to copycon

Contrarian’s submission to the National Consultation on Copyright focuses on an issue that has received little attention in the consultation, an area in which current Canadian law provides a striking lack of balance, an issue in which Canadian law is not decades but centuries out of date: the issue of Crown Copyright.

Visual data: the digital revolution in graphs – feedback

One of the great things about running a blog is that when you write about something interesting that you know little about, readers rush in with a wealth of further information. Contrarian friend Andrew Weissman directed us to an extraordinary TED talk by Hans Rosling illustrating the phenomenal potential of the digital graphs we touched on this morning.

Rosling is a professor of international medicine at Sweden’s Karolinska Institutet (the organization that hands out the Nobel Prize for Medicine). He discovered Konzo, a previously unknown paralytic disease associated with hunger in Africa. He also co-founded the Gapminder Foundation, which developed the Trendalyzer software that turns international health statistics into moving, interactive, and revelation-generating graphics for public use. Here’s a stunning example, from Rosling’s TED talk, “Hans Rosling shows the best stats you’ve ever seen.”

Notice how much data is compressed into the moving chart shown about three and a half minutes in. Each dot represents a country. The x-axis (horizontal) tracks the number of women per child in each county, a measure of family size. The y-axis (vertical) shows the percentage of a country’s children that survive to age five, a measure of health. The size of each dot represents its population, the color shows its region of the world.

When Rosling animates the chart, it brings 40+ years of history to life, starting in 1962. The dots become a beehive, moving purposefully through the decades. As they do, obscure trends in world health—many of them counter-intuitive—suddenly become obvious. Whereas the planet could aptly be divided into “developed world” and “third world” in 1962, Rosling shows that today’s world defies easy pigeon holes. Rosling’s software tools make sense of an otherwise impenetrable data set.

Well, don’t read about it. Watch the video.

Two years ago, Google purchased Trendalyzer. You can now add simple animated graphs to your website using a free Google Gadget called Motion Chart. Gapminder maintains a series of more sophisticated online tools to help people map world data they are prepared to share freely.
