Mind the gap.
Google’s Gapmider alows you to track nation’s population (circle size), per capita income (x-axis) and average life expectancy (y-axis) over the past thirty years. This particular link highlights the trails of:
- India: constant and slow growth in all areas.
- Luxembourg: notable income growth, tripled from $22k to $64k in thirty years.
- and Rwanda: fairly consistent population and income, but a life expectancy that ranges from 45 to 24 and back.
Interesting stuff.
There is one major gotcha in the visualization, the income values are highly compressed towards the right side of the scale. On the left a single pixel represents about $10, but on the right one pixel is about $10,000. A needed device to fit all the information in, but it does have a subconscious effect of making low income changes seem much more dramatic.
